The 12CWQ10FN 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.
