Description/Features
The 40EPS.. rectifier
SAFE
IR
series has been optimized
for very low forward voltage drop, with moderate leakage.
The glass passivation technology used has reliable opera-
tion up to 150° C junction temperature.
Typical applications are in input rectification and these
products are designed to be used with International
Rectifier Switches and Output Rectifiers which are available
in identical package outlines.
