Description/ Features
The 6CWQ03FN 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 re-
verse battery protection.
