AS1PG-M3/85A

Overview

The AS1PG-M3/85A is a surface-mount avalanche-rated rectifier from Vishay, housed in the DO-220AA (SMP) package. It features a 400 V DC reverse voltage and a 1.5 A average forward current rating. The device utilizes standard recovery technology with a maximum forward voltage of 950 mV at 1.5 A. It supports a peak repetitive reverse voltage of 400 V and operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Engineered with avalanche capability for robust energy handling during transient events
• Utilizes plastic molded compound meeting UL flammability classification 94V-0
• Designed for high reliability with low thermal resistance characteristics

Applications

• General-purpose rectification in power supply circuits
• Protection stages requiring avalanche ruggedness
• Surface-mount assembly for compact electronic devices

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS directives and REACH regulations as specified in the current datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when a standard recovery rectifier requires avalanche withstand capability in a compact SMP footprint. Compare the 1.5 A current rating and 400 V blocking voltage against circuit requirements to ensure adequate margin for peak loads and reverse bias conditions.

Part Context

This part belongs to the AS1Px series of avalanche rectifiers manufactured by Vishay General Semiconductor. These components are designed for applications demanding high reliability and surge immunity in small surface-mount packages, distinguishing them from non-avalanche variants within the broader diode portfolio.

Replacement Considerations

Consult official substitution lists for verified equivalents. Generic replacements may lack the specific avalanche rating or thermal performance required for this application.
