1SMA10CAT3G Series

Description

The 1SMA10CAT3G series is designed to protect voltage

sensitive components from high voltage, high energy

transients. They have excellent clamping capability, high

surge capability, low zener impedance and fast response

time. The 1SMA10CAT3G series is supplied in the

Littelfuse exclusive, cost-effective, highly reliable package

and is ideally suited for use in communication systems,

automotive, numerical controls, process controls, medical

equipment, business machines, power supplies and many

other industrial/consumer applications.

Features

• Working Peak Reverse Voltage Range − 10 V to 78 V
