• Industrial control system power stages

Single Diodes Procurement Notes

Verify the specific suffix 'R' against the official Microchip datasheet to confirm packaging details, as standard part numbers may vary in bulk or reel configurations. Ensure compliance with RoHS status indicated in the manufacturer's documentation prior to integration into regulated assemblies.

Single Diodes Selection Notes

Select this component when a 100 V reverse voltage rating and 20 A current capacity are required in a DO-203AB form factor. Consider the 0.2 µs reverse recovery speed for applications requiring faster switching than standard slow-recovery diodes but where ultra-fast speeds are unnecessary.

Single Diodes Part Context

This part belongs to the 1N39xx series of rectifier diodes produced by Microchip Technology. These components are widely utilized in industrial and commercial electronics for converting AC to DC. The DO-203AB package provides mechanical stability for high-current applications compared to smaller signal diode packages.

Single Diodes Replacement Considerations

Consult the official Microchip cross-reference guide for verified substitutes. Generic equivalents must match the 100 V reverse voltage, 20 A current rating, and DO-203AB package dimensions to ensure physical and electrical compatibility.
