1.5SMC6.8AT3G Datasheet, PDF (1/7 Pages) ON Semiconductor – 1500 Watt Peak Power Zener Transient Voltage Suppressors

1.5SMC6.8AT3G Series,
SZ1.5SMC6.8AT3G 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.
