MLA Automotive Varistor Series
RoHS
Description
The MLA Automotive Series 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 Automotive
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 Automotive Series suitable for numerous applications
on power supply, control and signal lines.
The MLA Automotive Series is manufactured from
semiconducting ceramics, and is supplied in a leadless,
surface mount package. The MLA Automtove Series
is compatible with modern reflow and wave soldering
procedures.

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

Clamping Voltage Over Temperature (VC at 10A)
Device Characteristics
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.

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
Automotive Series 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 Automotive 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 V26MLA1206 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
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 Automotive Series 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.

The recommended solder for the MLA Automotive Series
suppressor is a 62/36/2 (Sn/Pb/Ag), 60/40 (Sn/Pb) or 63/37

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.

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.

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.
