Procurement Notes

Verify the manufacturer source carefully as multiple entities distribute this part number. Confirm the specific datasheet version matches your design requirements, particularly regarding the package outline dimensions and thermal resistance values. Ensure the component meets any applicable military or industrial reliability standards if specified in your bill of materials.

Selection Notes

Select this component when a robust, high-current through-hole rectifier is required for 200 V applications. The TO-254AA package provides superior heat dissipation compared to smaller packages. Consider the 20 A continuous current rating against your circuit's load profile and ambient temperature conditions to ensure safe operating margins.

Part Context

This component belongs to the family of discrete silicon rectifiers manufactured by Microchip Technology. It serves as a fundamental building block in power electronics, offering a balance of current capacity and voltage blocking capability. The part is distinct from ultra-fast variants within the same numbering series, which feature different recovery times.

Replacement Considerations

Cross-reference with other 20 A, 200 V through-hole rectifiers in the TO-254AA package. Verify pinout compatibility and thermal performance metrics before substitution.
