## **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 like automotive applications. 

These diodes also fit into auxiliary functions such as snubber, bootstrap, and demagnetization applications.
