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.
