Single Diodes Procurement Notes

Verify the specific ordering suffix TRR indicates right-oriented tape and reel packaging for the D2PAK package. Confirm Pb-free status if required by environmental specifications. Ensure the component matches the Vishay document number 93123 for accurate technical data. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Single Diodes Selection Notes

Select this component for high-frequency switching applications requiring fast recovery characteristics. The D2PAK package provides efficient thermal management with a thermal resistance of 3.0 °C/W junction-to-case. Consider the 200 V blocking voltage and 8 A current rating against circuit requirements. Evaluate the soft recovery behavior to reduce electromagnetic interference in sensitive designs.

Single Diodes Part Context

This device belongs to Vishay's MURB series of ultrafast recovery rectifiers utilizing FRED Pt technology. The 'B' designation specifies the D2PAK surface-mount package, while '8' denotes the 8 A current rating and '20' indicates the 200 V voltage rating. The TRR suffix specifically identifies the right-oriented tape and reel packaging format for automated assembly.

Single Diodes Replacement Considerations

Consult official Vishay documentation for verified substitute part numbers. Generic replacements may not match the specific FRED Pt platinum doping or reverse recovery characteristics. Verify pinout compatibility between D2PAK variants and ensure thermal resistance ratings are equivalent for direct substitution.

Single Diodes FAQ

What is the difference between MURB820 and MURB820-1?

The MURB820 uses a D2PAK package, whereas the MURB820-1 utilizes a TO-262 package. Both share identical electrical characteristics and functionality.

What does the FRED Pt technology imply for this diode?

FRED Pt stands for Fast Recovery Epitaxial Diode with Platinum doping. This process controls carrier lifetime to achieve ultrafast recovery times and low reverse recovery charge, optimizing efficiency in high-frequency switching circuits.
