MLA Varistor Series
Description
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 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 plastic-
housed 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.
