DESCRIPTION

The 12CWQ04FNPbF 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, freewheeling diodes, battery charging, and
reverse battery protection.
