SAFEIR Series
40EPS..
INPUT RECTIFIER DIODE
VF
< 1.1V @ 40A
IFSM = 475A
VRRM = 800 - 1200V
Description/Features
The 40EPS.. rectifier SAFEIR series has been optimized
for very low forward voltage drop, with moderate leakage.
The glass passivation technology used has reliable operation 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.
