Procurement Notes
Verify the specific suffix configuration against official datasheets to ensure compatibility with your design requirements. Confirm that the DO-220AA package dimensions align with your PCB footprint specifications. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before finalizing procurement orders.
Selection Notes
Select this component when high-speed switching performance is critical for the application circuit. The 200 V rating suits low-voltage DC-DC converters and freewheeling diode roles. Consider the 1 A current capacity relative to thermal management constraints in the chosen enclosure. The AEC-Q100 qualification makes it suitable for automotive environments where reliability under varying temperatures is essential.
Part Context
This device belongs to the AU1P series of ultrafast recovery rectifiers from Vishay. The series is characterized by fast switching speeds and high reliability. The AU1PDHM3/84A variant specifically integrates avalanche capability, distinguishing it from standard rectifiers in the same family. It serves as a specialized solution for demanding power conversion tasks.
Replacement Considerations
The AU1PDHM3/85A is a documented substitute part number within the same product line. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure the alternative package or suffix meets all original design constraints.
