A180RN

Overview

The A180RN is a standard recovery rectifier diode manufactured by Powerex Inc. It features an 800 V maximum repetitive peak reverse voltage and a 150 A average rectified current rating. The device utilizes a DO-205AA (DO-8) stud mount package with a metal body, designed for base mounting. It operates within a junction temperature range of -40°C to 200°C. Key electrical characteristics include a maximum forward voltage of 1.3 V at 150 A and a non-repetitive peak forward surge current of 3400 A.

Feature Summary

• Standard recovery speed suitable for general-purpose rectification applications
• High thermal stability with a maximum junction temperature of 200°C
• Robust mechanical construction using a round metal post/stud mount package

Applications

• General purpose rectification circuits
• Industrial power conversion systems
• High-current DC power supplies

Procurement Notes

Verify the specific datasheet revision when sourcing, as Powerex documentation may vary in format across distributors. Confirm that the DO-205AA package dimensions match your mechanical design constraints. Ensure the ordering suffix corresponds to the exact terminal configuration required for your assembly process. Cross-reference the manufacturer part number against authorized distributor listings to guarantee authenticity and traceability.

Selection Notes

Select this component for applications requiring high current handling and robust thermal performance. The 800V rating provides sufficient margin for medium-voltage AC-to-DC conversion. Consider the stud mount requirement for your heatsinking strategy, as surface mount alternatives are not available in this form factor. Evaluate the standard recovery time against your switching frequency requirements to ensure acceptable reverse recovery losses.

Part Context

This component belongs to the A180 series of rectifier diodes from Powerex Inc., which includes variants like the A180N. The series is characterized by high current capabilities and durable packaging for industrial environments. These devices are engineered for reliability in demanding power electronics applications where long-term stability under high thermal stress is critical.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 150A current rating, 800V voltage rating, and DO-205AA package type. Verify that the replacement's thermal resistance and recovery characteristics meet or exceed the original specifications.
