Single Diodes Procurement Notes

Verify the specific suffix codes against the official Vishay datasheet to ensure correct voltage and current ratings. Confirm that the D-55 mounting interface matches your thermal design requirements. Check RoHS compliance status if required by your manufacturing standards. Ensure proper torque specifications are followed during installation to maintain electrical integrity.

Single Diodes Selection Notes

Select this component when a 200 V blocking voltage and 85 A continuous current are required in a chassis-mount configuration. Consider the D-55 package size for PCB or heatsink integration. Evaluate thermal resistance values from the datasheet to determine adequate cooling solutions. Compare reverse recovery characteristics against system switching frequencies to ensure compatibility.

Single Diodes Part Context

This part belongs to the T85HF series of high-current rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent current handling and packaging. The D-55 package is standard for industrial-grade power diodes requiring direct chassis mounting. This specific model provides a balance of voltage rating and current capacity for general-purpose power conversion.

Single Diodes Replacement Considerations

Direct substitutes may include other Vishay T85HF series variants with different voltage ratings, such as VS-T85HF80 or VS-T85HF160, provided the voltage margin is sufficient. Cross-brand replacements must match the 85 A current rating, 200 V minimum blocking voltage, and D-55 mechanical footprint. Verify pinout and thermal pad configurations before substitution.
