SZ1SMCxxA Series
Surface Mount > 1500W
TVS Diodes Datasheet
RoHS
Pb e3
Description
The SZ1SMC 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 SZ1SMC series is supplied in cost-effective, highly reliable DO-214AB 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.
