## **SS32 - S310 Schottky Rectifier** 

## **Features** 

- Metal to Silicon Rectifiers, Majority Carrier Conduction 

- Low-Forward Voltage Drop 

- Easy Pick and Place 

- High-Surge Current Capability 

## **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.

## **Absolute Maximum Ratings** 

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.
