AR3PD-M3/87A

Overview

The AR3PD-M3/87A is a surface-mount Avalanche Rectifier Diode manufactured by Vishay General Semiconductor - Diodes Division. It features a TO-277A (SMPC) package and is rated for a maximum repetitive peak reverse voltage of 200 V with an average forward rectified current of 1.8 A. The device exhibits a maximum forward voltage of 1.1 V at the rated current and a non-repetitive peak forward surge current capability of 60 A. It operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Engineered with avalanche-rated construction for robust energy handling capabilities
• Utilizes planar passivation technology for enhanced reliability and stability
• Designed for high-speed switching applications requiring fast recovery characteristics

Applications

• High-frequency power supply circuits
• Inductive load protection and snubber networks
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix /87A corresponds to the required reel packaging configuration, as suffixes often denote tape-and-reel quantities rather than functional changes. Confirm RoHS compliance status through the official datasheet before integration. Ensure the ordering quantity aligns with the manufacturer's standard reel size to avoid partial reel handling issues.

Selection Notes

Select this component when a surface-mount solution is required for 200 V applications needing avalanche ruggedness. The TO-277A package offers thermal performance advantages over smaller SMD cases while maintaining a compact footprint. Compare the 1.8 A current rating against circuit requirements to ensure adequate margin for continuous operation under expected thermal conditions.

Part Context

This diode belongs to Vishay’s AR series of surface-mount avalanche rectifiers. These devices are designed to withstand transient energy events without failure, making them suitable for harsh electrical environments. The SMPC package provides a balance between thermal dissipation and board space efficiency for modern electronic assemblies.

Replacement Considerations

The AR3PD-M3/86A is a verified alternative from the same manufacturer family. Verify that the packaging difference does not impact automated assembly processes. Ensure pinout compatibility remains identical between the /86A and /87A variants before substituting.
