MLA Automotive Varistor Series
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.

It can operate over a wider temperature range than Zener
diodes, and has a much smaller footprint than plastic-
housed components.

Device Characteristics
ClampingVoltage OverTemperature (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.

Energy Absorption/Peak Current Capability
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

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

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.
As a measure of the device capability in energy and peak
current handling, the V26MLA1206 part was tested with

the end of the test,10,000 pulses later, the device voltage
characteristics are still well within specification.

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

During the soldering process, preheating to within 100
degrees of the solder's peak temperature is essential to
minimize thermal shock.
