SCHOTTKY RECTIFIER
TO-247AC
Description/Features
ThiscentertapSchottkyrectifierhasbeenoptimized for ultra
low forward voltage drop specifically for 3.3V output power
supplies.Theproprietarybarriertechnologyallowsforreliable
operation up to 150 °C junction temperature. Typical
applications are in parallel switching power supplies,
converters, reverse battery protection, and redundant power
subsystems.
