1SMA5.0AT3G Series

Pb

Description

The 1SMA5.0AT3G 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 1SMA5.0AT3G 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.
