## **Features** 

- AEC-Q101 qualified 

- Ultrafast, soft recovery 

- Very low conduction and switching losses 

- High frequency and/or high pulsed current operation 

- High reverse voltage capability 

- High junction temperature 

- ECOPACK[®] compliant 

## **Applications** 

- On Board Battery charger (OBC) 

- Surge bypass diodes 

## **Description** 

The high quality design of this diode has produced a device with low leakage current, regularly reproducible characteristics and intrinsic ruggedness. These characteristics make it ideal for heavy duty applications that demand long term reliability. 

## **Product status link** ~~ea~~ 

The improved performance in low leakage current, and therefore thermal runaway guard band, is an immediate competitive advantage for this device for automotive applications.
