Features and Benefits
Patented SBR technology provides superior avalanche
capability versus 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.
<1.1mm Package Profile – ideal for thin applications.
Lead-Free Finish; RoHS Compliant (Notes 1 & 2)
Halogen and Antimony Free “Green” Device (Note 3)
Qualified to AEC-Q101 Standards for High Reliability
ADVANCED INFORMATIN
