Overview
The Powerex A430B is a general-purpose rectifier diode housed in the DO-200AB package. It features a 200V repetitive peak reverse voltage and a 1000A average forward current rating. The device exhibits a maximum forward voltage drop of 1.15V at rated current and a non-repetitive surge current capability of 18,000A. Operating characteristics include a maximum junction temperature of 175°C and a thermal resistance from junction to case of 0.006°C/W. The component utilizes a clamp-on mounting style with a single terminal configuration.
Feature Summary
- High-current handling capability for demanding power applications
- Electrically isolated chassis mount design for easy integration
- Robust construction ensuring durability under high stress conditions
Applications
- Industrial motor drives

- DC power supplies
Procurement Notes
Verify the specific datasheet version to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure the procurement channel provides original manufacturer documentation to validate authenticity. Confirm that the DO-200AB package matches the intended chassis or heatsink interface requirements for proper thermal management and secure installation.
Selection Notes
Select this component when high average current and low voltage drop are required in a ruggedized package. The DO-200AB form factor supports direct chassis mounting, simplifying thermal path design. Consider the 175°C junction temperature limit for high-ambient environments. Verify that the 200V reverse voltage rating exceeds the circuit's peak inverse voltage requirements with adequate safety margin.
Part Context
This part belongs to Powerex's discrete rectifier lineup, designed for phase control and general rectification. The series emphasizes high efficiency and reliability in industrial settings. The DO-200AB package is standard for high-power silicon devices requiring robust mechanical stability and efficient heat dissipation through direct contact with cooling surfaces.
Replacement Considerations
Cross-reference with other 1000A, 200V DO-200AB rectifiers from manufacturers like Semikron or Mitsubishi. Verify matching forward voltage drops and thermal resistance values to ensure equivalent performance without redesigning the cooling system.
