AS3PG-M3/86A

Overview

The AS3PG-M3/86A is a standard recovery rectifier from Vishay, rated for 400V reverse voltage and 3A average forward current. It utilizes the eSMP (TO-277A) surface-mount package. Key electrical parameters include a maximum forward voltage of 1V at 3A, a peak surge current capability of 70A, and a low reverse leakage current of 280nA. The device features a single cathode dual anode configuration with a typical reverse recovery time of 1.2µs. It operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Glass passivated chip junction ensures stable performance and reliability under various operating conditions.
• Controlled avalanche characteristics provide robust protection against transient voltage events.
• Low leakage current minimizes power loss during reverse bias operation.
• High forward surge capability supports handling of inrush currents without damage.

Applications

• Automotive electronics systems requiring AEC-Q101 qualification
• General-purpose rectification in industrial power supplies
• DC-DC converter circuits utilizing surface-mount assembly

Procurement Notes

Verify the specific suffix /86A corresponds to the required tape-and-reel packaging format before ordering. Confirm RoHS compliance status and REACH SVHC declarations align with target market regulations. Ensure the SMPC (TO-277A) footprint matches the PCB design guidelines provided in the official datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to prevent sourcing errors.

Selection Notes

Select this component when a high-current density standard rectifier with avalanche rating is needed in a low-profile SMD package. The 400V rating suits medium-voltage DC applications. Consider the 1.2µs recovery time for general frequency operations rather than high-frequency switching. The dual anode configuration allows for specific circuit topologies requiring common cathode connections.

Part Context

This device belongs to the AS3P series of high current density standard avalanche surface mount rectifiers. The series is designed for automated placement due to its very low profile. It represents Vishay's eSMP product line, combining high thermal performance with compact mechanical dimensions suitable for modern dense PCB layouts.

Replacement Considerations

Check for direct substitutes within the AS3P family offering different voltage ratings or configurations. Verify pinout compatibility if replacing with other TO-277A devices. Ensure any alternative maintains the same avalanche characteristic requirements and thermal management specifications.
