Description/Features
The 50WQ03FN surface mount Schottky rectifier 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.
