Zener Transient Voltage Suppressors
The SMC 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 SMC series is supplied in Motorola’s
exclusive, cost-effective, highly reliable Surmetic package and is ideally suited for use in
communication systems, numerical controls, process controls, medical equipment,
business machines, power supplies and many other industrial/consumer applications.
