Single Diodes Procurement Notes

Verify the specific suffix BR against official Microchip documentation to confirm exact packaging or material specifications, as generic part numbers may encompass multiple variants. Confirm RoHS compliance status directly from the manufacturer datasheet, as historical data indicates potential non-compliance for certain series revisions. Ensure the procurement channel provides valid traceability documents matching the Microchip manufacturing lot codes.

Single Diodes Selection Notes

Select this component for applications requiring high-temperature operation up to 200°C junction temperature. The 12 A current rating and 400 V blocking voltage define its electrical limits. Verify that the mechanical design accommodates the DO-203AA stud mount configuration. Consider the standard recovery speed for compatibility with the target switching frequency requirements.

Single Diodes Part Context

The 1N1204BR belongs to the 1N1204 series of axial leaded and stud mount silicon rectifiers produced by Microchip Technology.
