SMCJ70A 二极管 Littelfuse

SMCJ70A

ESD 抑制器/TVS 二极管 70Vr 1500W 13.3A 5% UniDirectional

Surface Mount – 1500W > SMCJ series

The SMCJ70A SMCJ series is designed specifically to protect

sensitive electronic equipment from voltage transients

induced by lightning and other transient voltage events.

SMCJ70A  Applications

TVS devices are ideal for the protection of I/O Interfaces,

VCC bus and other vulnerable circuits used in Telecom,

Computer, Industrial and Consumer electronic

applications.
