Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging details. Ensure the procurement channel provides valid traceability for automotive-grade components. Confirm that the received units match the specified SMPC package dimensions and pinout configuration before integration into the design.

Selection Notes

Select this component when a surface mount solution with controlled avalanche behavior is required. The SMPC package offers a low profile suitable for automated placement processes. Consider the 1.2 us recovery time and 3 A current rating to ensure compatibility with the target circuit's switching frequency and load requirements.

Part Context

This part belongs to the eSMP series of high current density standard avalanche surface mount rectifiers. The series is designed for applications demanding reliability and compact form factors. Vishay utilizes specific manufacturing processes to achieve the controlled avalanche characteristics and low leakage currents documented for this product line.

Replacement Considerations

Consult official Vishay substitution guides for verified equivalents. Cross-referencing requires matching the 3 A current rating, 400 V reverse voltage, and SMPC package type. Verify that any substitute maintains the same avalanche qualification status and thermal performance characteristics.
