## **FEATURES** 

- I Negligible switching losses 

- I Low forward voltage drop 

- I Low capacitance 

- I High reverse avalanche surge capability 

## **DESCRIPTION** 

High voltage dual Schottky rectifier suited for switchmode power supplies and other power converters. Packaged in TO-220AB, this device is intended for use in medium voltage operation, and particularly, in high frequency circuitries where low switching losses and low noise are required.
