Description/Features
The 10MQ090 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.
Small foot print, surface mountable
Low forward voltage drop
High frequency operation
Guard ring for enhanced ruggedness and long term
reliability
