Major Ratings and Characteristics
Characteristics
Description/ Features
The 10MQ040N surface mount Schottky rectifier has been designed for applications requiring low forward drop and very 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.
