The 12CWQ03FN surface mount, center tap, Schottky rectifier 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 reverse battery protection.
