DESCRIPTION
The VS-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, freewheeling diodes, battery
charging, and reverse battery protection.
