Single Diodes Procurement Notes

Verify the specific suffix 'RA' against the official datasheet to confirm it denotes the correct variant, as packaging or minor parameter differences may exist between similar part numbers. Ensure the procurement channel provides traceability documentation required for industrial components. Confirm that the DO-4 stud mount configuration matches the thermal management design of the target application board.

Single Diodes Selection Notes

Select this component when a 200 V, 12 A rectifier with stud mount capability is required. Compare the 1.2 V forward voltage drop against system efficiency targets. Verify that the 10 µA reverse leakage specification meets the circuit's isolation requirements. Ensure the mounting hardware supports the thermal dissipation needs associated with the 200°C junction limit.

Single Diodes Part Context

This component belongs to Microchip's legacy discrete semiconductor line, specifically the standard rectifier category. It serves as a rugged solution for medium-current power electronics where reliability under high thermal loads is critical. The DO-4 package is a traditional form factor often found in heavy-duty industrial equipment and older power supply designs requiring durable, screw-mounted diodes.

Single Diodes Replacement Considerations

Consult the official Microchip datasheet for cross-reference tables. Potential substitutes must match the 200 V reverse voltage, 12 A current rating, and DO-4 stud mount footprint. Verify that any replacement maintains the same standard recovery time characteristics to avoid switching issues in existing circuits.
