The 6CWQ04FNPbF 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.
