Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm compliance requirements. The base part number indicates commercial grade specifications. Confirm that the TR3 designation corresponds to the required tape and reel packaging format before finalizing procurement orders.

Selection Notes

Select this component for designs requiring fast switching speeds and high reliability in compact form factors. Ensure the circuit operating voltage remains below the 200 V maximum repetitive peak reverse voltage rating. Verify thermal management capabilities align with the specified junction-to-case thermal resistance values under expected load conditions.

Part Context

This component belongs to the BYG series of fast avalanche SMD rectifiers produced by Vishay. The series utilizes the SMA (DO-214AC) case configuration. The M3 suffix denotes halogen-free and RoHS-compliant materials. The product line supports various voltage ratings including 200 V, 400 V, and 600 V options within the same package family.

Replacement Considerations

Cross-reference with other Vishay SMA packaged fast recovery diodes sharing identical electrical parameters. Verify pinout compatibility and physical dimensions match the SMA (DO-214AC) footprint. Confirm equivalent reverse recovery times and avalanche energy ratings for direct substitution.
