Procurement Notes
Verify the specific ordering code suffix against the manufacturer's official documentation to confirm compliance requirements. The base part number HM3 indicates AEC-Q101 qualification availability, while M3 denotes commercial grade. Ensure the selected variant matches the required packaging format and revision code before finalizing procurement specifications.
Selection Notes
Select this component for designs requiring ultrafast recovery times and avalanche ruggedness within a compact surface mount footprint. The TO-277A package provides efficient thermal dissipation for high-frequency operations. Evaluate the 600 V reverse voltage rating against circuit peak inverse voltages to ensure adequate safety margins under transient conditions.
Part Context
This device belongs to the eSMP Series of ultrafast rectifiers manufactured by Vishay General Semiconductor. It utilizes glass passivation technology to achieve fast reverse recovery and low leakage currents. The product line is designed to meet modern electronics demands for high efficiency and compact form factors in power conversion systems.
Replacement Considerations
Direct substitutes include AU3PDHM3/86A and AU3PGHM3/86A from the same series, which share identical physical dimensions and electrical ratings except for their maximum repetitive peak reverse voltage specifications of 200 V and 400 V respectively.
