Overvoltage

Transient Suppressor

Designed for applications requiring a low voltage rectifier with

reverse avalanche characteristics for use as reverse power transient

suppressors. Developed to suppress transients in the automotive

system, these devices operate in the forward mode as standard

rectifiers or reverse mode as power avalanche rectifier and will protect

electronic equipment from overvoltage conditions.

Features
