Overview
The Vishay AU3PMHM3/86A is an ultrafast avalanche surface mount rectifier in the eSMP series. It features a glass passivated pellet chip junction and operates with a maximum repetitive peak reverse voltage of 1000 V and a DC forward current of 3.0 A. The device exhibits a fast reverse recovery time of 75 ns and supports non-repetitive avalanche energy up to 20 mJ at 2.5 A. Packaged in SMPC (TO-277A), it withstands a peak forward surge current of 45 A and functions within a temperature range of -55 °C to +175 °C.
Feature Summary
- Controlled avalanche characteristics for robust operation under transient conditions
- Ultrafast reverse recovery time suitable for high-frequency applications
- Glass passivated chip junction providing stable electrical performance
- Low profile design optimized for automated placement processes
Applications
- Fast switching rectification in power supplies
- Freewheeling diodes in inverters and converters
- Automotive lighting circuits
- Telecommunication equipment power stages
Procurement Notes
Verify that the ordering code includes the HM3 suffix to confirm AEC-Q101 automotive qualification. Ensure the package designation matches the required reel size, as the base part number may be supplied in different packaging configurations. Confirm compliance requirements against specific project standards before finalizing procurement orders.
Selection Notes
Select this component when high voltage blocking capability and avalanche ruggedness are required in a compact surface mount form factor. The 1000 V rating distinguishes it from lower voltage variants in the same series. Consider the thermal resistance values when designing heat dissipation strategies for high ambient temperatures or dense PCB layouts.
Part Context
This device belongs to the Vishay eSMP series of ultrafast rectifiers designed for space-constrained applications. It utilizes the SMPC (TO-277A) package to provide high current density in a small footprint. The product line targets industries requiring reliable switching performance and strict adherence to automotive quality standards.
Replacement Considerations
AU3PKHM3/86A serves as a direct substitute with an 800 V reverse voltage rating instead of 1000 V. Verify that the reduced voltage rating meets the circuit's peak inverse voltage requirements before implementing any cross-model replacements.
