Single Diodes Procurement Notes

Verify component authenticity through authorized Microchip Technology distributors or certified suppliers. Confirm RoHS non-compliance status aligns with specific application requirements. Validate datasheet revisions against manufacturing change notices prior to procurement to ensure technical specifications remain consistent with design intent.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating and 100 A continuous current capacity are required. Ensure the mounting interface accommodates the DO-205AA stud configuration. Consider the 1.55 V forward voltage drop for thermal management calculations within the system design constraints.

Single Diodes Part Context

This part belongs to the 1N3288–1N3297 series of high-current rectifiers manufactured by Microchip Technology. These components share similar mechanical footprints and recovery characteristics while varying primarily in voltage ratings. The series supports demanding power electronics environments requiring reliable high-amperage switching.

Single Diodes Replacement Considerations

Cross-reference with other members of the 1N3288–1N3297 series if voltage or current ratings differ. Verify pinout compatibility and thermal resistance values before substituting with equivalent parts from other manufacturers.
