AR3PJ-M3/86A

Overview

The AR3PJ-M3/86A is a fast switching avalanche surface-mount rectifier from Vishay General Semiconductor. It features a single circuit configuration in an SMPC (TO-277A) package. Key electrical parameters include a maximum repetitive peak reverse voltage of 600 V, a maximum DC forward current of 3.0 A, and a peak forward surge current of 50 A. The device exhibits a typical instantaneous forward voltage of 1.04 V at 3.0 A and 125 °C, with a maximum reverse recovery time of 140 ns. It supports an operating junction temperature range from -55 °C to +175 °C.

Feature Summary

• Glass passivated pellet chip junction for enhanced reliability
• Controlled avalanche characteristics for robust performance under transient conditions
• Very low profile design suitable for automated placement processes
• High forward surge capability combined with low leakage current

Applications

• Fast switching rectification in power supplies
• Freewheeling diodes in inverters and converters
• Lighting applications
• Consumer, automotive, and telecommunication equipment

Procurement Notes

Verify the specific ordering code against the manufacturer's official documentation to ensure correct package quantity and delivery mode. Confirm that the M3 suffix aligns with RoHS compliance and halogen-free requirements. Check for any regional technical support contacts if application-specific validation is required before finalizing procurement.

Selection Notes

Select this component when high voltage blocking up to 600 V is required alongside fast reverse recovery characteristics. The TO-277A package offers a compact footprint ideal for space-constrained designs. Ensure thermal management accounts for the specified junction-to-ambient resistance. Validate avalanche energy ratings against potential transient events in the target circuit.

Part Context

This part belongs to the eSMP series of fast switching avalanche rectifiers manufactured by Vishay General Semiconductor. The series utilizes glass passivation technology and is designed for surface-mount assembly. The AR3PJ variant specifically denotes the 600 V rating within the family that also includes lower voltage options.

Replacement Considerations

Direct substitutes within the same series include AR3PD (200 V) and AR3PG (400 V), provided the voltage rating meets the circuit requirements. Verify pinout compatibility and thermal characteristics when cross-referencing with other manufacturers' TO-277A packages.
