PCHMB400W6

Overview

The PCHMB400W6 is a single IGBT module manufactured by KYOCERA AVX, designed for high-power switching applications. It features a maximum collector-emitter voltage of 650 V and a continuous collector current rating of 400 A at 25°C. The device incorporates an integrated FRD within a buck chopper circuit configuration. Key electrical parameters include a collector-emitter saturation voltage of 1.45 V and a maximum gate-emitter voltage of 20 V. The module utilizes silicon technology and supports a maximum operating temperature of +150°C.

Feature Summary

• Integrates an IGBT with a fast recovery diode (FRD) in a single package
• Configured specifically for buck chopper circuit topologies
• Utilizes screw mount installation style for secure chassis attachment

Applications

• Industrial motor drives
• Power supply systems requiring buck chopper configurations
• High-current switching applications in industrial equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific environmental declarations such as SVHC non-use if required for your assembly process. Ensure the supplier provides valid traceability documentation to guarantee the integrity of the silicon components and packaging materials used in this high-power module.

Selection Notes

Select this module when a combined IGBT and FRD solution is needed for buck chopper circuits. The 650V rating suits medium-voltage industrial applications. Consider the 400A current capacity and 1.45V saturation voltage for thermal management calculations. Verify that the screw mount footprint matches the mechanical design constraints of the target chassis or heatsink assembly before finalizing the design.

Part Context

This component belongs to the KYOCERA AVX IGBT module series, which focuses on high-power discrete and module solutions. These modules are engineered for robust performance in demanding environments, offering integrated protection features like the built-in FRD. The product line supports various industrial sectors requiring reliable power conversion and control.

Replacement Considerations

The PRFMB200W6 is a related single IGBT module from the same manufacturer but offers different current ratings and includes a brake chopper circuit instead of a buck chopper configuration. Direct substitution requires careful evaluation of the specific circuit topology requirements and current handling capabilities.
