AU1PD-M3/84A

Overview

The AU1PD-M3/84A is a surface-mount ultra-fast avalanche rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1 A. The device utilizes the DO-220AA (SMP) package, ensuring compatibility with standard surface-mount assembly processes. It is designed for high-reliability applications requiring robust avalanche energy handling capabilities.

Feature Summary

• Ultra-fast recovery characteristics suitable for high-frequency switching applications
• Avalanche-rated construction for enhanced ruggedness in inductive load scenarios
• Surface-mount DO-220AA (SMP) package for automated assembly efficiency

Applications

• Secondary rectification in switched-mode power supplies
• Freewheeling diodes in DC-DC converters
• High-frequency rectification circuits

Procurement Notes

Verify the specific suffix 'M3' confirms RoHS compliance and halogen-free status as per Vishay standards. Confirm the '/84A' designation corresponds to the tape-and-reel packaging format required for your assembly line equipment. Cross-reference the manufacturer part number against the latest datasheet revision to ensure no obsolescence notices or PCNs affect availability or material composition.

Selection Notes

Select this component when circuit design requires both fast recovery times and avalanche capability within a compact surface-mount footprint. Ensure the operating junction temperature range of -55°C to 175°C aligns with the thermal management strategy of the target application. Verify that the 200 V reverse voltage rating provides sufficient margin above the maximum expected peak inverse voltage in the circuit.

Part Context

This component belongs to Vishay's eSMP series of surface-mount rectifiers. It shares the DO-220AA physical footprint with other variants in the family but is distinguished by its specific electrical ratings and avalanche tolerance. The product line targets modern electronics manufacturing where space constraints and reliability under transient conditions are critical design parameters.

Replacement Considerations

Direct substitutes include other Vishay 1A 200V SMP rectifiers such as the ES1PD-M3/84A, though functional differences exist regarding avalanche capability. Verify pinout compatibility and thermal resistance characteristics before substituting with components from other manufacturers.
