Description/ Features
The 40EPS..PbF rectifier
SAFE
IR
series has been opti-
mized for very low forward voltage drop, with moderate
leakage. The glass passivation technology used has reli-
able 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.
