Description/ Features

The 12CWQ03FN surface mount, center tap, Schottky recti-

fier series has been designed for applications requiring low

forward drop and small foot prints on PC board. Typical

applications are in disk drives, switching power supplies,

converters, free-wheeling diodes, battery charging, and re-

verse battery protection.
