Description
The SZ1.5SMC 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 SZ1.5SMC series is supplied in the exclusive,
cost-effective, highly reliable Littelfuse 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.
