1SMA5.0AT3 Series

400 Watt Peak Power Zener

Transient Voltage Suppressors

Unidirectional*

The SMA 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 SMA series is supplied in

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

Surmetic

t 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.
