AS1PG-M3/84A

Overview

The AS1PG-M3/84A is a single avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a DO-220AA (SMP) surface-mount package and supports an average forward current of 1.5 A with a maximum repetitive peak reverse voltage of 400 V. The device exhibits a maximum forward voltage of 1.6 V at 1.5 A and a non-repetitive peak surge current capability of 40 A. It operates within a junction temperature range of -55°C to +175°C, ensuring reliability in high-temperature environments.

Feature Summary

• Engineered with avalanche-rated characteristics for robust energy handling during transient events
• Utilizes the eSMP® surface-mount technology for efficient PCB integration
• Designed for high thermal stability with an extended operating junction temperature range

Applications

• High-voltage switching power supplies requiring avalanche resilience
• Flyback converter circuits in consumer electronics
• Inductive load protection in automotive systems

Procurement Notes

Verify the specific suffix against official Vishay documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with RoHS3 standards if required by your manufacturing process. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm lead times and availability status through verified supply chain channels before finalizing procurement plans.

Selection Notes

Select this component when circuit design demands a standard recovery rectifier capable of withstanding avalanche energy without failure. Compare its 400 V rating and 1.5 A current capacity against alternative packages to ensure mechanical fit. Evaluate the thermal performance requirements relative to the DO-220AA footprint. Consider the specific avalanche energy ratings provided in the datasheet for your application's stress conditions.

Part Context

This component belongs to the AS1P series of avalanche rectifiers from Vishay. These devices are specifically designed to handle repetitive avalanche breakdown conditions, distinguishing them from standard rectifiers that may fail under similar transient stresses. The series offers various voltage ratings within the same compact SMP package family.

Replacement Considerations

AS1PJ-M3/84A is a documented variant within the same product line offering different voltage specifications.
