Single Diodes Procurement Notes

Verify the specific datasheet revision and RoHS compliance status before procurement. Confirm that the D-55 mounting interface matches the heatsink requirements. Ensure the selected variant meets the required voltage and current ratings for the target application. Check for any recent product change notices regarding manufacturing sites or specifications.

Single Diodes Selection Notes

Select this component for applications requiring high current handling in a compact stud-mount form factor. The 400V rating suits low-voltage AC/DC conversion tasks. Consider the 1.27V forward voltage drop for thermal management calculations. Ensure adequate cooling solutions are designed around the D-55 package to maintain junction temperatures within safe limits during continuous operation.

Single Diodes Part Context

This part belongs to the T85 series of high-current rectifiers from Vishay. The series offers various voltage ratings while maintaining consistent current capabilities and packaging standards. The D-55 package provides a standardized footprint for easy integration into existing power electronics designs requiring robust diode solutions.

Single Diodes Replacement Considerations

Direct substitutes must match the 85A current rating, 400V voltage rating, and D-55 package type. Verify equivalent forward voltage and reverse leakage characteristics. Consult Vishay documentation for approved cross-references or updated series replacements.
