A180RP

Overview

The A180RP is a general-purpose silicon rectifier diode manufactured by Powerex Inc. It features a maximum repetitive peak reverse voltage of 1000 V and an average forward rectified current of 150 A. The device utilizes a stud mount configuration within the DO-205AA (DO-8) package. Key electrical characteristics include a maximum non-repetitive surge current of 3000 A at 60 Hz for half-sine waves, a maximum DC reverse leakage current of 20 mA at rated voltage, and a typical junction-to-case thermal resistance of 0.14 °C/W. The component operates within a junction temperature range of -40°C to +200°C.

Feature Summary

• High-voltage rectification capability with 1000 V reverse blocking rating
• Robust current handling with 150 A average forward current capacity
• Stud mount construction for efficient thermal dissipation and mechanical stability
• Extended operating junction temperature range up to 200°C

Applications

• Industrial power conversion systems
• General-purpose rectification in high-voltage circuits
• DC power supply input stages

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical ratings, as variations exist within the A180 series. Confirm package compatibility and mounting hardware requirements prior to integration. Ensure sourcing channels provide authentic components with traceable manufacturing data to guarantee reliability in critical power applications.

Selection Notes

Select this component when a standard recovery rectifier with 1000 V blocking capability and 150 A continuous current is required. Evaluate thermal management solutions based on the specified junction-to-case thermal resistance. Compare against alternative series members if different voltage or current ratings better suit the specific circuit design constraints.

Part Context

This part belongs to the A180 series of silicon rectifiers from Powerex Inc., designed for robust industrial applications. The series includes variants with different voltage ratings, such as the A180RN (800 V). These devices are characterized by their high surge current capability and durable stud-mount packaging, making them suitable for demanding power electronics environments requiring reliable long-term operation.

Replacement Considerations

Direct substitutes may include other 1000 V, 150 A stud-mount rectifiers from manufacturers like Microsemi or Vishay, provided pinout and thermal characteristics match. Verify that replacement parts meet or exceed the original 3000 A surge current rating and 200°C junction temperature limit.
