MLA Varistor Series
RoHS
The MLA Series (also known as "ML" series) family of
transient voltage surge suppression devices is based on
the Littelfuse Multilayer fabrication technology. These
components are designed to suppress a variety of
transient events, including those specified in IEC 61000-4-2
or other standards used for Electromagnetic Compliance
(EMC). The MLA Series is typically applied to protect
integrated circuits and other components at the circuit
board level.
The wide operating voltage and energy range make the
MLA Series suitable for numerous applications on power
supply, control and signal lines.

The MLA Series is manufactured from semiconducting
ceramics, and is supplied in a leadless, surface mount
package. The MLA Series is compatible with modern
reflow and wave soldering procedures.
It can operate over a wider temperature range than Zener
diodes, and has a much smaller footprint than plastichoused components.
Littelfuse Inc. manufactures other multilayer series
products. See the MLE Series data sheet for ESD
applications, MHS Series data sheet for high-speed ESD
applications, the MLN Series for multiline protection and
the AUML Series for automotive applications.

When transients occur in rapid succession, the average
power dissipation is the energy (watt-seconds) per pulse
times the number of pulses per second. The power so
developed must be within the specifications shown
on the Device Ratings and Specifications Table for the

temperature, the peak surge current and energy ratings
must be derated as shown below.

Clamping Voltage Over Temperature (VC at 10A)
At low current levels, the V-I curve of the multilayer
transient voltage suppressor approaches a linear (ohmic)
relationship and shows a temperature dependent effect.
At or below the maximum working voltage, the suppressor
is in a high resistance modex (approaching 106Ω at its
maximum rated working voltage). Leakage currents at
maximum rated voltage are below 100μA, typically 25μA;
for 0402 size below 20μA, typically 5μA.

SUPPRESSOR CURRENT (ADC)
Speed of Response
The Multilayer Suppressor is a leadless device. Its
response time is not limited by the parasitic lead
inductances found in other surface mount packages.
The response time of the ZNO dielectric material is less
than 1ns and the MLA can clamp very fast dV/dT events
such as ESD. Additionally, in "real world" applications,
the associated circuit wiring is often the greatest
factor effecting speed of response. Therefore, transient
suppressor placement within a circuit can be considered
important in certain instances.
Energy dissipated within the MLA Series is calculated
by multiplying the clamping voltage, transient current
and transient duration. An important advantage of the
multilayer is its interdigitated electrode construction within
the mass of dielectric material. This results in excellent
current distribution and the peak temperature per energy
absorbed is very low. The matrix of semiconducting grains
combine to absorb and distribute transient energy (heat)
(see Speed of Response). This dramatically reduces peak
temperature; thermal stresses and enhances device
reliability.
As a measure of the device capability in energy and peak
current handling, the V26MLA1206A part was tested with
multiple pulses at its peak current rating (150A, 8/20μs). At
the end of the test,10,000 pulses later, the device voltage
characteristics are still well within specification.

Lead (Pb) Soldering Recommendations
The principal techniques used for the soldering of
components in surface mount technology are IR Re-flow
and Wave soldering. Typical profiles are shown on the right.
Reflow Solder Profile
250
MAXIMUM TEMPERATURE
230°C
The recommended solder for the MLA suppressor is
a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37 (Sn/Pb).
Littelfuse also recommends an RMA solder flux.
TEMPERATURE °C
200
Wave soldering is the most strenuous of the processes.
To avoid the possibility of generating stresses due to
thermal shock, a preheat stage in the soldering process
is recommended, and the peak temperature of the solder
process should be rigidly controlled.
When using a reflow process, care should be taken to
ensure that the MLA chip is not subjected to a thermal
gradient steeper than 4 degrees per second; the ideal
gradient being 2 degrees per second. During the soldering
process, preheating to within 100 degrees of the solder's
peak temperature is essential to minimize thermal shock.

Once the soldering process has been completed, it is
still necessary to ensure that any further thermal shocks
are avoided. One possible cause of thermal shock is hot
printed circuit boards being removed from the solder
process and subjected to cleaning solvents at room
temperature. The boards must be allowed to cool gradually
to less than 50º C before cleaning.

Lead–free (Pb-free) Soldering Recommendations
Littelfuse offers the Nickel Barrier Termination option (see
"N" suffix in Part Numbering System for ordering) for the
optimum Lead–free solder performance, consisting of a
Matte Tin outer surface plated on Nickel underlayer, plated
on Silver base metal.

TEMPERATURE °C
The preferred solder is 96.5/3.0/0.5 (SnAgCu) with an RMA
flux, but there is a wide selection of pastes and fluxes
available with which the Nickel Barrier parts should be
compatible.
The reflow profile must be constrained by the maximums
in the Lead–free Reflow Profile. For Lead–free wave
soldering, the Wave Solder Profile still applies.
Note: the Lead–free paste, flux and profile were used for
evaluation purposes by Littelfuse, based upon industry
standards and practices. There are multiple choices of all
three available, it is advised that the customer explores the
optimum combination for their process as processes vary
considerably from site to site.
