The Mitsubishi CM450DX-24S is a 450A, 1200V IGBT module engineered for high-current power switching in industrial and commercial power electronics systems. This dual or chopper-configuration module delivers low saturation voltage and fast switching characteristics, making it well-suited for applications where thermal management, switching losses, and long-term reliability are critical design parameters. The CM450DX-24S follows Mitsubishi's proven CM-series platform, offering engineers a dependable solution that integrates cleanly into established drive architectures and converter topologies.

The CM450DX-24S sees wide deployment across heavy industrial environments including AC and DC motor drives, regenerative braking systems, medium-voltage inverters, induction heating equipment, and uninterruptible power supplies. Its 1200V blocking voltage and 450A current rating make it a practical fit for three-phase converter stages in steel mills, paper mills, mining equipment, and rail traction systems. OEM machine builders and MRO procurement teams regularly specify this module when upgrading aging drive systems or maintaining equipment originally designed around the Mitsubishi CM-series IGBT platform.

Quick Reference: CM450DX-24S

Key Features of the CM450DX-24S:

• 1200V collector-emitter voltage (VCES) supports high-bus-voltage inverter designs with adequate derating margin
• 450A continuous collector current rating suitable for high-power motor drive and converter stages
• Low VCE(sat) characteristics reduce conduction losses and thermal stress at full load
• Integrated freewheeling diodes optimized for fast reverse recovery, minimizing switching losses in PWM applications
• Industry-standard isolated base plate package simplifies heatsink mounting and thermal interface design
• Compatible with established Mitsubishi CM-series gate drive circuits, enabling direct drop-in replacement in legacy systems

With a current factory lead time of 43 weeks on new production orders, procurement teams supporting active production lines or critical MRO needs cannot rely on the standard supply chain for the CM450DX-24S. Obsolescence risk is real for CM-series modules as Mitsubishi transitions product roadmaps, and unplanned downtime on a high-power drive system carries significant cost. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time IGBT modules precisely for these situations, providing a reliable source when the factory cannot respond in time.

ATI Accurate Technology is located in Palmetto, Florida and specializes in IGBTs, thyristors, diodes, and rectifier modules — including obsolete and long-lead-time parts.
