SCHOTTKY RECTIFIER
5.5 Amp
Description/Features
Major Ratings and Characteristics
The 50WQ..F 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.
