## Schottky Rectifier 

## SS32 - S310 

## **Description** 

The SS32−S310 series includes a high−efficiency, low power loss, general−propose Schottky rectifiers. The clipbonded leg structure provides high thermal performance and low electrical resistance. These rectifiers are suited for free wheeling, secondary rectification, and reverse polarity protection applications.
