Terminations
1.1
Nickel barrier termination
The nickel barrier layer of the silver/nickel/tin termination prevents leaching of the silver base metallization layer. This allows great flexibility in the selection of soldering parameters. The tin prevents the nickel layer from oxidizing and thus ensures better wetting by the solder. The nickel barrier termination is suitable for all commonly-used soldering methods.
Multilayer CTVS: Structure of nickel barrier termination
1.2
Silver-palladium termination
Silver-palladium terminations are used for the large case sizes 1812 and 2220 and for chips intended for conductive adhesion. This metallization improves the resistance of large chips to thermal shock.
In case of conductive adhesion, the silver-palladium metallization reduces susceptibility to corrosion. Silver-palladium termination can be used for smaller case sizes (only chip) for hybrid applications as well. The silver-palladium termination is not approved for lead-free soldering.

Silver-platinum terminations are mainly used for the large case sizes 1812 and 2220. The silverplatinum termination is approved for reflow soldering, SnPb soldering and lead-free soldering with
a silver containing solder paste. In case of SnPb soldering, a solder paste Sn62Pb36Ag2 is recommended. For lead-free reflow soldering, a solder paste SAC, e.g. Sn95.5Ag3.8Cu0.7, is recommended.

Solder joint profiles / solder quantity
4.1
Nickel barrier termination
If the meniscus height is too low, that means the solder quantity is too low, the solder joint may
break, i.e. the component becomes detached from the joint. This problem is sometimes interpreted as leaching of the external terminations.
If the solder meniscus is too high, i.e. the solder quantity is too large, the vise effect may occur.
As the solder cools down, the solder contracts in the direction of the component. If there is too
much solder on the component, it has no leeway to evade the stress and may break, as in a vise.
The figures below show good and poor solder joints for dual-wave and infrared soldering.

Conductive adhesion
Attaching surface-mounted devices (SMDs) with electrically conductive adhesives is a commercially attractive method of component connection to supplement or even replace conventional soldering methods.
Electrically conductive adhesives consist of a non-conductive plastic (epoxy resin, polyimide or
silicon) in which electrically conductive metal particles (gold, silver, palladium, nickel, etc) are embedded. Electrical conduction is effected by contact between the metal particles.
Adhesion is particularly suitable for meeting the demands of hybrid technology. The adhesives
can be deposited ready for production requirements by screen printing, stamping or by dispensers. As shown in the following table, conductive adhesion involves two work operations fewer
than soldering.

A further advantage of adhesion is that the components are subjected to virtually no temperature
shock at all. The curing temperatures of the adhesives are between 120 °C and 180 °C, typical
curing times are between 30 minutes and one hour.
The bending strength of glued chips is, in comparison with that of soldered chips, higher by a factor of at least 2, as is to be expected due to the elasticity of the glued joints.
The lower conductivity of conductive adhesive may lead to higher contact resistance and thus result in electrical data different to those of soldered components. Users must pay special attention
to this in RF applications.

Note:
Leaching of the termination
Effective area at the termination might be lost if the soldering temperature and/or immersion time
are not kept within the recommended conditions. Leaching of the outer electrode should not exceed 25% of the chip end area (full length of the edge A-B-C-D) and 25% of the length A-B,

Notes for proper soldering
7.1
Preheating and cooling
According to JEDEC J-STD-020D. Please refer to chapter 2.
7.2
Repair / rework
Manual soldering with a soldering iron must be avoided, hot-air methods are recommended for
rework purposes.
7.3
Cleaning
All environmentally compatible agents are suitable for cleaning. Select the appropriate cleaning
solution according to the type of flux used. The temperature difference between the components
and cleaning liquid must not be greater than 100 °C. Ultrasonic cleaning should be carried out
with the utmost caution. Too high ultrasonic power can impair the adhesive strength of the metallized surfaces.
7.4
Solder paste printing (reflow soldering)
An excessive application of solder paste results in too high a solder fillet, thus making the chip
more susceptible to mechanical and thermal stress. Too little solder paste reduces the adhesive
strength on the outer electrodes and thus weakens the bonding to the PCB. The solder should be
applied smoothly to the end surface.

Important notes at the end of this document.

Multilayer varistors (MLVs)
Standard series
7.5
Adhesive application
Thin or insufficient adhesive causes chips to loosen or become disconnected during curing.
Low viscosity of the adhesive causes chips to slip after mounting. It is advised to consult the
manufacturer of the adhesive on proper usage and amounts of adhesive to use.
7.6
Selection of flux
Used flux should have less than or equal to 0.1 wt % of halogenated content, since flux residue
after soldering could lead to corrosion of the termination and/or increased leakage current on the
surface of the component. Strong acidic flux must not be used. The amount of flux applied should
be carefully controlled, since an excess may generate flux gas, which in turn is detrimental to solderability.
7.7
Storage of CTVSs
Solderability is guaranteed for one year from date of delivery for multilayer varistors, CeraDiodes
and ESD/EMI filters (half a year for chips with AgPd and AgPt terminations) and two years for
SHCV and CU components, provided that components are stored in their original packages.
Storage temperature:
25 °C to +45 °C
Relative humidity:
≤75% annual average, ≤95% on 30 days a year
The solderability of the external electrodes may deteriorate if SMDs and leaded components are
stored where they are exposed to high humidity, dust or harmful gas (hydrogen chloride, sulfurous
acid gas or hydrogen sulfide).
Do not store SMDs and leaded components where they are exposed to heat or direct sunlight.
Otherwise the packing material may be deformed or SMDs/ leaded components may stick together, causing problems during mounting.
After opening the factory seals, such as polyvinyl-sealed packages, it is recommended to use the
SMDs or leaded components as soon as possible.
7.8
Placement of components on circuit board
Especially in the case of dual-wave soldering, it is of advantage to place the components on the
board before soldering in that way that their two terminals do not enter the solder bath at different
times.
Ideally, both terminals should be wetted simultaneously.
7.9
Soldering cautions
An excessively long soldering time or high soldering temperature results in leaching of the outer
electrodes, causing poor adhesion and a change of electrical properties of the varistor due to
the loss of contact between electrodes and termination.
Wave soldering must not be applied for MLVs designated for reflow soldering only.
Keep the recommended down-cooling rate.

Cautions and warnings
General
Some parts of this publication contain statements about the suitability of our ceramic transient
voltage suppressor (CTVS) components (multilayer varistors (MLVs), CeraDiodes, ESD/EMI
filters, SMD disk varistors (CU types), leaded transient voltage/ RFI suppressors (SHCV types))
for certain areas of application, including recommendations about incorporation/design-in of these
products into customer applications. The statements are based on our knowledge of typical
requirements often made of our CTVS devices in the particular areas. We nevertheless expressly
point out that such statements cannot be regarded as binding statements about the suitability of
our CTVS components for a particular customer application. As a rule, EPCOS is either unfamiliar
with individual customer applications or less familiar with them than the customers themselves.
For these reasons, it is always incumbent on the customer to check and decide whether the
CTVS devices with the properties described in the product specification are suitable for use in a
particular customer application.
Do not use EPCOS CTVS components for purposes not identified in our specifications,
application notes and data books.
Ensure the suitability of a CTVS in particular by testing it for reliability during design-in. Always
evaluate a CTVS component under worst-case conditions.
Pay special attention to the reliability of CTVS devices intended for use in safety-critical
applications (e.g. medical equipment, automotive, spacecraft, nuclear power plant).
Design notes
Always connect a CTVS in parallel with the electronic circuit to be protected.
Consider maximum rated power dissipation if a CTVS has insufficient time to cool down
between a number of pulses occurring within a specified isolated time period. Ensure that
electrical characteristics do not degrade.
Consider derating at higher operating temperatures. Choose the highest voltage class
compatible with derating at higher temperatures.
Surge currents beyond specified values will puncture a CTVS. In extreme cases a CTVS will
burst.
If steep surge current edges are to be expected, make sure your design is as low-inductance
as possible.
In some cases the malfunctioning of passive electronic components or failure before the end of
their service life cannot be completely ruled out in the current state of the art, even if they are
operated as specified. In applications requiring a very high level of operational safety and
especially when the malfunction or failure of a passive electronic component could endanger
human life or health (e.g. in accident prevention, life-saving systems, or automotive battery line
applications such as clamp 30), ensure by suitable design of the application or other measures
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of such a malfunction or failure. Only use CTVS components from the
automotive series in safety-relevant applications.
Please read Cautions and warnings and
Important notes at the end of this document.

Standard series
Specified values only apply to CTVS components that have not been subject to prior electrical,
mechanical or thermal damage. The use of CTVS devices in line-to-ground applications is
therefore not advisable, and it is only allowed together with safety countermeasures like
thermal fuses.
Storage
Only store CTVS in their original packaging. Do not open the package before storage.
Storage conditions in original packaging: temperature 25 to +45°C, relative humidity ≤75%
annual average, maximum 95%, dew precipitation is inadmissible.
Do not store CTVS devices where they are exposed to heat or direct sunlight. Otherwise the
packaging material may be deformed or CTVS may stick together, causing problems during
mounting.
Avoid contamination of the CTVS surface during storage, handling and processing.
Avoid storing CTVS devices in harmful environments where they are exposed to corrosive
gases for example (SOx, Cl).
Use CTVS as soon as possible after opening factory seals such as polyvinyl-sealed packages.
Solder CTVS components after shipment from EPCOS within the time specified:
CTVS with Ni barrier termination, 12 months
CTVS with AgPd and AgPt termination, 6 months
SHCV and CU series, 24 months
Handling
Do not drop CTVS components and allow them to be chipped.
Do not touch CTVS with your bare hands - gloves are recommended.
Avoid contamination of the CTVS surface during handling.
Mounting
When CTVS devices are encapsulated with sealing material or overmolded with plastic
material, electrical characteristics might be degraded and the life time reduced.
Make sure an electrode is not scratched before, during or after the mounting process.
Make sure contacts and housings used for assembly with CTVS components are clean before
mounting.
The surface temperature of an operating CTVS can be higher. Ensure that adjacent
components are placed at a sufficient distance from a CTVS to allow proper cooling.
Avoid contamination of the CTVS surface during processing.
Multilayer varistors (MLVs) with AgPd termination are not approved for lead-free soldering.
Soldering
Complete removal of flux is recommended to avoid surface contamination that can result in an
instable and/or high leakage current.
Use resin-type or non-activated flux.
Bear in mind that insufficient preheating may cause ceramic cracks.
Rapid cooling by dipping in solvent is not recommended, otherwise a component may crack.

Conductive adhesive gluing
Only multilayer varistors (MLVs) with an AgPd termination are approved for conductive
adhesive gluing.
Operation
Use CTVS only within the specified operating temperature range.
Use CTVS only within specified voltage and current ranges.
Environmental conditions must not harm a CTVS. Only use them in normal atmospheric
conditions. Reducing the atmosphere (e.g. hydrogen or nitrogen atmosphere) is prohibited.
Prevent a CTVS from contacting liquids and solvents. Make sure that no water enters a CTVS
(e.g. through plug terminals).
Avoid dewing and condensation.
EPCOS CTVS components are mainly designed for encased applications. Under all
circumstances avoid exposure to:
direct sunlight
rain or condensation
steam, saline spray
corrosive gases
atmosphere with reduced oxygen content
EPCOS CTVS devices are not suitable for switching applications or voltage stabilization where
static power dissipation is required.
Multilayer varistors (MLVs) are designed for ESD protection and transient suppression.
CeraDiodes are designed for ESD protection only, ESD/EMI filters are designed for ESD and
EMI protection only.

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar
with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or

requiring a very high level of operational safety and especially in customer applications in
which the malfunction or failure of an electronic component could endanger human life or
health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by
means of suitable design of the customer application or other action taken by the customer
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of malfunction or failure of an electronic component.
3. The warnings, cautions and product-specific notes must be observed.
