1SMB5.0AT3 Series
600 Watt Peak Power Zener
Transient Voltage
Suppressors
Unidirectional*
The SMB 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 SMB 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.
