Characteristics Value Units

The MBRS340TR 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.

Small foot print, surface mountable

Very low forward voltage drop

High frequency operation

Guard ring for enhanced ruggedness and long term

reliability
