Description/ Features
The 6CWQ10FN 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.
