Procurement Notes

Verify the specific suffix against official documentation to confirm package type and compliance status. Confirm availability through authorized distributors as lead times may vary. Ensure the ordering part number matches the required voltage and current ratings for your specific circuit design requirements.

Selection Notes

Select this component for applications requiring high voltage blocking capabilities combined with fast switching speeds. The TO-277A-3 package offers a compact footprint suitable for space-constrained designs. Consider the 175°C operating limit for high-temperature environments where standard silicon limits might be exceeded.

Part Context

This part belongs to the AR3P series of fast recovery rectifiers manufactured by Vishay General Semiconductor. The series is designed for high-efficiency power applications, featuring robust construction and reliable performance under demanding electrical conditions typical of modern electronic systems.

Replacement Considerations

Consult official substitution guides for verified equivalents. Generic replacements must match the 800V rating, 3A current capacity, and TO-277A-3 package dimensions to ensure compatibility.
