Description/ Features
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.
