1.5SMC6.8AT3 Series

1500 Watt Peak Power

Zener Transient Voltage

Suppressors

Unidirectional*

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

ON Semiconductor’s exclusive, cost-effective, highly reliable

Surmetic

™ 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.
