SM2T3V3A

Low voltage Transil™

Features

■ unidirectional Transil diode

■ high peak pulse power: 200 w (10/1000 µs)

■ stand-off voltage 3.3 V

■ low clamping factor V

■

fast response time

■ JEDEC registered package outline

Description

The SM2T3V3A is a Transil diode designed

specifically for portable equipment and

miniaturized electronic devices subject to ESD

transient overvoltages. It's low stand-off voltage

makes it suitable for low voltage applications very

sensitive to EOS and ESD events.

Transil diodes provide high overvoltage protection

by clamping action.
