SCHOTTKY RECTIFIER
Major Ratings and Characteristics
Description/Features
The 20FQ Schottky rectifier series has been optimized for
very low forward voltage drop, with moderate leakage. The
proprietarybarriertechnologyallowsforreliableoperationup
to 150° C junction temperature. Typical applications are in
switchingpowersupplies,converters,free-wheelingdiodes,
and reverse battery protection.
