SZ1SMA Series

Description

The SZ1SMA series is designed to protect voltage

Bi-directional

sensitive components from high voltage, high energy

transients. They have excellent clamping capability, high

surge capability, low zener impedance and fast response

time. The SZ1SMA 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 and consumer applications.
