Single Diodes Procurement Notes

Verify the specific suffix codes against the official datasheet to ensure correct packaging and compliance status. Confirm that the D-55 module form factor matches your thermal management and mounting requirements. Cross-reference the UL file number E78996 if regulatory certification is mandatory for your end product. Ensure sourcing channels provide genuine Vishay components to guarantee specified electrical parameters.

Single Diodes Selection Notes

Select this component when applications require a 2200 V blocking capability combined with a 20 A continuous current rating. The T-Module package is suitable for chassis mounting where high thermal dissipation and electrical isolation are critical. Consider the 18 mA reverse leakage specification for high-voltage standby conditions. Evaluate the junction temperature limit of 150°C against your system's thermal profile to ensure reliable long-term operation under load.

Single Diodes Part Context

This part belongs to Vishay’s FRED Pt® (Fast Recovery Epitaxial Diode) family, which utilizes platinum doping to control carrier lifetime. The T-Module designation indicates a standardized industrial housing designed for easy integration into larger power assemblies. The D-55 package provides a compact footprint while maintaining high voltage isolation capabilities essential for medium-to-high power electronic systems.

Single Diodes Replacement Considerations

Consult official Vishay documentation for direct cross-references. Verify that any substitute maintains the 2200 VRRM and 20A Io ratings. Ensure the replacement also offers an electrically isolated base plate and compatible D-55 mechanical dimensions. Check for equivalent reverse recovery characteristics to maintain circuit stability.
