Overview
The AR3PK-M3/87A is a standard recovery avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V maximum repetitive peak reverse voltage and a 3 A average forward rectified current rating. The device utilizes the eSMP package, specifically TO-277A-3, for surface mount applications. It is designed with avalanche capability to withstand repetitive avalanche energy conditions. The component operates within a junction temperature range of -55°C to +150°C and is RoHS compliant.
Feature Summary
- Incorporates avalanche capability for handling repetitive avalanche energy
- Utilizes eSMP (TO-277A-3) surface mount package technology
- Designed for high reliability in standard recovery applications
Applications
- General purpose rectification in power supplies
- Protection circuits requiring avalanche ruggedness
- Automotive electronics applications
Procurement Notes
Verify the specific suffix /87A corresponds to the reel packaging configuration as defined in the official datasheet. Confirm RoHS compliance status through the manufacturer's current documentation. Ensure the ordering quantity aligns with the factory pack quantity requirements specified by Vishay Semiconductors for this particular part number.
Selection Notes
Select this component when an 800 V blocking voltage and 3 A continuous current are required in a compact surface mount footprint. The avalanche rating makes it suitable for inductive load switching where transient energy absorption is necessary. Compare thermal resistance characteristics against system heat dissipation capabilities to ensure reliable operation at elevated temperatures up to 150°C.
Part Context
This device belongs to the AS3P series of standard recovery rectifiers from Vishay. It represents a surface mount alternative to through-hole packages, offering similar electrical performance in a smaller form factor. The eSMP packaging allows for automated placement and improved PCB space efficiency compared to traditional axial or DO-style packages.
Replacement Considerations
Cross-reference with AR3PM variants for pinout compatibility. Verify that substitute parts maintain the 800 V reverse voltage and 3 A current ratings. Ensure any replacement also supports the required avalanche energy specifications if used in inductive switching environments.
