Overview
The Vishay AU2PMHM3/86A is an ultrafast avalanche surface mount rectifier in the eSMP series. It features a single diode configuration within a SMPC (TO-277A) package. The device supports a maximum repetitive peak reverse voltage of 1000 V and a maximum DC forward current of 2.0 A. Key electrical characteristics include a typical reverse recovery time of 75 ns, a peak forward surge current capability of 30 A, and a non-repetitive avalanche energy rating of 20 mJ at 2.5 A. It operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Features controlled avalanche characteristics for robust performance under transient conditions.
- Utilizes glass passivated pellet chip junction technology for reliability.
- Designed with a very low profile suitable for automated placement processes.
- Complies with automotive qualification standards for enhanced durability.
Applications
- Fast switching rectification in power supplies
- Freewheeling diodes for inverters and converters
- Lighting applications
- Telecommunication equipment
Procurement Notes
Verify that the ordering code includes the HM3 suffix to confirm AEC-Q101 automotive qualification status. Ensure the base part number matches the specific voltage rating required for the application. Confirm compliance with RoHS directives and halogen-free material definitions as specified in the manufacturer documentation before finalizing procurement specifications.
Selection Notes
Select this component when high-frequency switching and avalanche ruggedness are required in a compact surface-mount form factor. The TO-277A package provides efficient thermal dissipation for continuous currents up to 2.0 A. Consider the 1000 V reverse voltage rating for high-voltage DC link applications where standard recovery times may introduce excessive losses.
Part Context
This component belongs to the Vishay eSMP series of ultrafast rectifiers. It shares the SMPC (TO-277A) mechanical footprint with other devices in the family, such as the AU2PK and AU2PM variants. The HM3 designation specifically denotes the AEC-Q101 qualified version, distinguishing it from commercial grade parts while maintaining identical electrical pinouts and dimensions.
Replacement Considerations
Direct substitutes within the same package and qualification level include the AU2PKHM3_A/H variant, which offers an 800 V rating instead of 1000 V. Verify that any replacement maintains the required avalanche energy rating and reverse recovery time specifications for the target circuit design.
FAQ
What is the non-repetitive avalanche energy rating?
The device has a non-repetitive avalanche energy rating of 20 mJ when tested with a current of 2.5 A at a junction temperature of 25 °C.
Does this component meet automotive standards?
Yes, the AU2PMHM3/86A is AEC-Q101 qualified, making it suitable for automotive applications requiring high reliability.
