SAC Series

The SAC Series is designed specifically to protect sensitive

electronic equipment from voltage transients induced by

lightning and other transient voltage events.

Description

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.
