< 1V @ 20A
IFSM = 475A
VRRM = 800 - 1200V
Description/ Features
The 40EPS..PbF 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.
