Characteristics MBRA140TR Units

The MBRA140TR 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
