Procurement Notes

Verify the specific ordering suffix against the official Microchip datasheet to ensure correct packaging and compliance status. Confirm that the required lead time aligns with production schedules, as availability may vary. Ensure the procurement channel provides valid manufacturer traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a high-current, high-voltage through-hole rectifier is required. Compare the 15 A average forward current and 500 V reverse voltage ratings against circuit demands. Consider the TO-254 package constraints for board space and thermal management requirements relative to alternative surface-mount solutions.

Part Context

This part belongs to the Microchip 1N series of discrete semiconductor diodes. It serves as a legacy replacement or equivalent for standard JEDEC-rated rectifiers in industrial and commercial electronics. The product line emphasizes reliability and robust performance in demanding electrical environments.

Replacement Considerations

Consult the official Microchip cross-reference list for verified substitutes. Ensure any replacement matches the 15 A current rating, 500 V voltage rating, and TO-254 package dimensions.
