MLA Auto Series

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.

It can operate over a wider temperature range than Zener

diodes, and has a much smaller footprint than plastic-

housed components.

Peak Current and Energy Derating Curve

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
