Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm packaging quantity and revision status. Ensure that the selected component meets the required AEC-Q101 qualification standards if intended for automotive environments. Cross-reference the datasheet revision date to validate thermal and electrical parameters prior to final procurement decisions.

Selection Notes

Select this component for designs requiring high voltage blocking capability combined with fast switching speeds. The SMPC package provides a compact footprint suitable for space-constrained PCB layouts. Consider the thermal resistance values when designing heat dissipation strategies for high ambient temperature environments or continuous high-current operation scenarios.

Part Context

This part belongs to the eSMP series of ultrafast avalanche rectifiers manufactured by Vishay General Semiconductor. It shares the same physical package and general performance characteristics as the AU3PD and AU3PG variants, differentiated primarily by their maximum repetitive peak reverse voltage ratings. The HM3 suffix indicates AEC-Q101 qualification for automotive applications.

Replacement Considerations

Direct substitutes include other Vishay parts within the AU3P family such as AU3PDHM3_A/I and AU3PGHM3_A/I, provided the lower voltage ratings are acceptable for the circuit design. Verify pinout compatibility and thermal management requirements before implementing any alternative components.
