Characteristics 40L..CW Units

Major Ratings and Characteristics

Description/ Features

The 40L..CW center tap Schottky rectifier has been optimized

for very low forward voltage drop, with moderate leakage. The

proprietary barrier technology allows for reliable operation up

to 150° C junction temperature. Typical applications are in

switching power supplies.
