Description/ Features
Units
A
The 30WQ04FNPbF 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.
