A180RD

Single Diodes Overview

The Powerex A180RD is a general-purpose rectifier diode designed for high-current industrial applications. It features an 800 V maximum repetitive peak reverse voltage and supports a continuous average forward current of 150 A. The device utilizes a DO-205AA (DO-8) stud mount package with a metal base, ensuring robust thermal dissipation. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 3400 A and a maximum forward voltage drop of 1.3 V at rated current. Operating temperatures range from -40 °C to +200 °C junction temperature.

Single Diodes Feature Summary

• High surge current capability for demanding power conversion environments
• Stud mount construction for efficient heat transfer and mechanical stability
• Extended junction temperature rating for reliable operation under thermal stress

Single Diodes Applications

• Industrial motor drives and variable frequency drives
• General purpose rectification in power supplies
• Inverter circuits and DC link applications

Single Diodes Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging variations. Ensure that the mounting hardware and torque specifications align with the DO-205AA stud requirements. Confirm RoHS compliance status if required by your manufacturing standards, as availability may vary by production batch.

Single Diodes Selection Notes

Select this component when a single-phase silicon rectifier with high current handling and rugged mechanical mounting is required. The 800 V rating suits medium-voltage AC-to-DC conversion tasks. Consider the thermal resistance of the stud mount interface during heatsink selection to maintain junction temperatures within the specified 200 °C limit under continuous load conditions.

Single Diodes Part Context

This part belongs to the A180 series of high-power rectifiers manufactured by Powerex Inc. The series is characterized by its use in heavy-duty industrial electronics where reliability under high thermal and electrical stress is critical. The DO-205AA package is a standard form factor for stud-mounted power diodes, facilitating integration into large-scale power modules and discrete cooling assemblies.

Single Diodes Replacement Considerations

Consult official cross-reference lists for equivalent parts with matching 150 A current and 800 V voltage ratings in a stud-mount configuration. Verify that any substitute maintains identical pinout polarity and thermal interface dimensions to ensure compatibility with existing mounting structures.
