Description and Applications

This Super Barrier Rectifier (SBR) diode has been designed to meet the
stringent requirements of Automotive Applications. It is ideally suited to
use as:

 Polarity Protection Diode
 Re-circulating Diode
 Switching Diode

Features and Benefits

 100% Avalanche Tested.
 Patented SBR technology provides a superior avalanche

capability than schottky diodes ensuring more rugged and reliable
end applications.

 Reduced Ultra-low forward voltage drop (V

cooler operation.

 Reduced high temperature reverse leakage; Increased reliability

against thermal runaway failure in high temperature operation

 Lead-Free Finish; RoHS Compliant (Notes 1 & 2)
 Halogen and Antimony Free. “Green” Device (Note 3)
 Qualified to AECQ101
