Characteristics 40L45CW Units
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. The proprietary barrier technology allows for reliable
operation up to 150° C junction temperature. Typical applica-
tions are in switching power supplies.
