1SMC5.OAT3 Datasheet, PDF (1/8 Pages) ON Semiconductor – Peak Power Zener Transient Voltage Suppressors
1SMC5.0AT3 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.
Specification Features:
• Working Peak Reverse Voltage Range – 5.0 V to 78 V
• Standard Zener Breakdown Voltage Range – 6.7 V to 91.25 V
• Peak Power – 1500 Watts @ 1 ms
