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
F
); better efficiency
and 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 AEC-Q101 Standards for High Reliability
