MLA Series

MLA Varistor Series

RoHS

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 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 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.

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
