DESCRIPTION

The VS-20MQ040-M3 surface mount Schottky rectifier has

been designed for applications requiring low forward drop

and very small foot prints on PC boards. Typical

applications are in disk drives, switching power supplies,

converters, freewheeling diodes, battery charging, and

reverse battery protection.
