Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm compliance status. The HM3 designation indicates halogen-free, RoHS-compliant material categorization and qualification under AEC-Q101 standards. Confirm package codes and delivery modes match project requirements before finalizing procurement actions.

Selection Notes

Select this component for designs requiring ultrafast recovery times and avalanche ruggedness within a compact surface mount footprint. Ensure thermal management strategies account for the specified junction-to-ambient resistance values. Validate that the 600 V reverse voltage rating exceeds peak circuit voltages under all operating conditions.

Part Context

This part belongs to the eSMP series of ultrafast avalanche rectifiers. It shares the SMPC package form factor with other variants like AU3PD and AU3PG, differentiated primarily by their reverse voltage ratings. The series targets high-frequency power conversion applications where fast switching and robustness are critical.

Replacement Considerations

Direct substitutes within the same family include AU3PDHM3_A/H and AU3PGHM3_A/H. Verify that alternative part numbers meet the required 600 V reverse voltage specification and maintain compatible thermal and mechanical characteristics for the intended application.
