These Super Barrier Rectifier (SBR®) diodes have been designed to meet the stringent requirements of automotive applications. They are ideally suited to use as: polarity protection diodes, re-circulating diodes, and switching diodes.


  • 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 (VF); better efficiency and cooler operation.
  • Reduced high-temperature reverse leakage; increased reliability against thermal runaway failure at high temperature
  • Lead-Free Finish; RoHS Compliant (Notes 1 & 2)
  • Halogen and Antimony Free. “Green” Device (Note 3)
  • The SBR1045D1Q is suitable for automotive applications requiring specific change control; this part is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. https://www.diodes.com/quality/product-definitions/


  • Polarity protection diodes
  • Re-circulating diodes
  • Switching diodes
