Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm qualification status. The HM3 suffix indicates AEC-Q101 qualification, while the base P/N-M3 denotes commercial grade. Ensure compliance with halogen-free and RoHS requirements as specified in the mechanical data section before procurement.

Selection Notes

Select this component for applications requiring ultrafast recovery and avalanche ruggedness within a low-profile surface mount form factor. Consider the thermal resistance values and derating curves when designing for high ambient temperatures or constrained PCB pad areas. Validate junction capacitance and reverse leakage specifications against circuit requirements.

Part Context

This part belongs to the eSMP series of ultrafast avalanche surface mount rectifiers manufactured by Vishay General Semiconductor. It utilizes the SMPC (TO-277A) case style, which provides a compact footprint suitable for automated placement. The series includes variants with different voltage ratings, such as AU2PD and AU2PG, sharing similar electrical characteristics and physical dimensions.

Replacement Considerations

Direct substitutes include AU2PDHM3_A/H and AU2PGHM3_A/H from the same family, offering identical packaging and general features but with lower voltage ratings of 200 V and 400 V respectively. Verify that the application voltage does not exceed the replacement's VRRM rating.
