The 6CWQ03FNPbF 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.
