Major Ratings and Characteristics
Description/Features
The 40L45CW center tap Schottky rectifier has been opti-
mized for very low forward voltage drop, with moderate
leakage.Theproprietarybarriertechnologyallowsforreliable
operationupto150°Cjunctiontemperature. Typicalapplica-
tions are in switching power supplies.
