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.
