Overview
The Vishay AR3PMHM3/87A is a fast switching avalanche surface-mount rectifier in the eSMP series. It features a single diode configuration within an SMPC (TO-277A) package. The device supports a maximum repetitive peak reverse voltage of 1000 V and a maximum DC forward current of 3.0 A. It exhibits a typical reverse recovery time of 120 ns and handles a peak forward surge current of 50 A. The component operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Glass passivated pellet chip junction for enhanced reliability
- Controlled avalanche characteristics for robust performance
- Very low profile design suitable for automated placement
- Halogen-free and RoHS-compliant construction
Applications
- Fast switching rectification of power supplies
- Inverters and converters
- Freewheeling diodes for consumer, automotive, and telecommunication equipment
- Lighting applications
Procurement Notes
Verify that the ordering code includes the HM3 suffix to confirm AEC-Q101 qualification for automotive use. Ensure the base part number matches AR3PM for the 1000 V rating. Confirm the delivery mode corresponds to the required reel size, as the 87A suffix indicates a specific tape and reel quantity. Cross-reference the document revision date with your procurement specifications.
Selection Notes
Select this component when high reverse voltage blocking capability and fast switching speeds are required in a compact surface-mount form factor. The controlled avalanche characteristic makes it suitable for inductive load switching. Verify thermal management requirements against the specified junction-to-ambient thermal resistance values for your specific PCB layout.
Part Context
This device belongs to the Vishay eSMP series of fast switching avalanche rectifiers. It utilizes the SMPC (TO-277A) package, which offers a low-profile alternative to traditional through-hole packages while maintaining high current handling capabilities. The series is designed for applications requiring reliable operation under high thermal stress and fast transient conditions.
Replacement Considerations
AR3PKHM3/87A: Identical package and electrical characteristics except for a lower maximum repetitive peak reverse voltage rating of 800 V compared to the 1000 V rating of the AR3PM variant.
