Overview
The Powerex A180RB is a general-purpose rectifier diode designed for high-current applications. It features an 800 V maximum repetitive peak reverse voltage and supports a continuous forward current of 150 A. The device utilizes a stud mount configuration within the DO-205AA (DO-8) package, ensuring robust mechanical stability. Constructed from silicon, it operates reliably across a junction temperature range of -40°C to +200°C. With a maximum non-repetitive peak forward surge current of 3400 A and a typical forward voltage drop of 1.3 V at rated current, this component provides efficient power conversion in demanding industrial environments.
Feature Summary
- High thermal endurance with a maximum junction temperature rating of 200°C
- Robust surge handling capability with a peak forward surge current of 3400 A
- Stud mount construction for secure installation and effective heat dissipation
Applications
- Industrial motor drives and variable frequency drives
- Welding equipment power supplies
- General purpose rectification in heavy-duty power systems
Procurement Notes
Verify the specific suffix against official datasheets to confirm exact electrical characteristics and packaging details. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before procurement. Ensure mounting hardware compatibility with the stud mount interface.
Selection Notes
Select this component for circuits requiring high current capacity and rugged reliability. The 150 A rating and 800 V blocking voltage suit medium-to-high power applications. Consider the stud mount requirement for PCB design and ensure adequate heatsinking to maintain junction temperatures within the specified operating range during continuous operation.
Part Context
This part belongs to the A180 series of general-purpose rectifiers manufactured by Powerex Inc. The series is characterized by high current handling and durable metal case constructions suitable for harsh environments. The A180RB variant specifically denotes the standard recovery time configuration within this lineup.
Replacement Considerations
Cross-reference with other 150 A, 800 V stud-mount rectifiers from manufacturers such as Littelfuse or Vishay. Verify that substitute parts match the physical dimensions, terminal configurations, and thermal performance specifications.
