Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package type matches the required G-4 form factor. Ensure the specific lot code aligns with current production standards, as availability may vary due to lifecycle status. Cross-reference electrical parameters such as reverse voltage and forward current to confirm suitability for the target circuit design before finalizing procurement.

Selection Notes

Select this component when a 200 V blocking voltage and 3 A continuous current are required in a through-hole configuration. Consider the 2 us reverse recovery time for applications where switching speed is not critical but high reliability is needed. Evaluate the operating temperature range to ensure compatibility with the environmental conditions of the final assembly.

Part Context

This part belongs to the general-purpose silicon rectifier family manufactured by Microchip Technology. It utilizes axial leaded construction suitable for automated or manual insertion processes. The device is engineered for robustness in industrial and commercial power conversion environments requiring reliable unidirectional current flow.

Replacement Considerations

Verify pinout compatibility and electrical ratings against potential substitutes. Ensure any replacement maintains the same package style and thermal characteristics. Consult manufacturer cross-reference lists for approved equivalents that meet identical performance criteria.
