DESCRIPTION
The VS-20BQ030-M3 surface mount Schottky rectifier has
been designed for applications requiring low forward drop
and small foot prints on PC boards. Typical applications are
in disk drives, switching power supplies, converters,
freewheeling diodes, battery charging, and reverse battery
protection.
