Description/ Features

The 30WQ03FN 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.
