Single Diodes Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to ensure correct variant selection. Confirm RoHS compliance status as indicated in technical specifications. Validate package dimensions and mounting requirements prior to integration. Ensure compatibility with existing thermal management solutions given the stud-mount design. Review manufacturing change notices for any recent updates to material composition or sourcing.

Single Diodes Selection Notes

Select this component when a 400 V reverse voltage rating and 12 A continuous current capacity are required. The DO-203AA package is appropriate for applications needing direct chassis mounting for heat dissipation. Consider the 150 ns reverse recovery time for switching frequency limitations. Evaluate thermal resistance parameters to determine adequate heatsinking for the intended operating environment.

Single Diodes Part Context

The 1N3893R belongs to the 1N3889–1N3893 series of standard recovery rectifiers manufactured by Microchip Technology. This series provides reliable performance for medium-to-high power rectification tasks. The 'R' suffix typically denotes a specific packaging or testing variation within the product line. These devices are engineered for durability in demanding industrial and military-grade applications.

Single Diodes Replacement Considerations

Consult official substitution guides for equivalent parts from Microchip or other manufacturers. Verify that alternative components match the 400 V reverse voltage, 12 A current rating, and DO-203AA package footprint. Ensure reverse recovery time and thermal characteristics meet or exceed original specifications.
