Description/ Features
Major Ratings and Characteristics
Characteristics
30BQ040 Units
The 30BQ040 surface-mount Schottky rectifier has been designed for applications requiring low forward drop and small
foot prints on PC boards. Typical applications are in disk drives,
switching power supplies, converters, free-wheeling diodes,
battery charging, and reverse battery protection.
