The Mitsubishi CM1200HC-66H is a high-capacity IGBT module rated at 1200 amperes and 3300 volts, engineered to meet the rigorous demands of high-power industrial switching applications. Manufactured by Mitsubishi Electric, this module integrates advanced IGBT and free-wheeling diode technology into a robust, industry-standard package. Its combination of high current handling, low saturation voltage, and excellent thermal characteristics makes it a preferred choice for engineers designing or maintaining high-efficiency power conversion systems operating at the upper end of the voltage and current envelope.

The CM1200HC-66H is widely deployed across heavy industrial sectors requiring reliable high-power conversion. Typical applications include medium-voltage variable frequency drives (VFDs), regenerative converters, traction inverters for rail and heavy equipment, industrial UPS systems, wind and solar power inverters, and static VAR compensators (SVCs). Its high blocking voltage of 3300V makes it especially suitable for direct connection in medium-voltage bus architectures where lower-voltage modules would require series stacking and additional complexity in gate drive and protection circuitry.

Quick Reference: CM1200HC-66H

Key Features of the CM1200HC-66H:

• 3300V collector-emitter breakdown voltage (VCES) for medium-voltage bus compatibility without series stacking
• 1200A continuous collector current rating supporting high-power inverter and converter topologies
• Low VCE(sat) characteristics reduce conduction losses and improve overall system efficiency at full load
• Integrated high-speed free-wheeling diodes optimized for low reverse recovery charge (Qrr), minimizing switching losses
• Isolated AlN (aluminum nitride) or equivalent ceramic baseplate construction for superior thermal conductivity and long-term reliability under cyclic thermal stress
• Industry-standard module footprint and terminal layout for straightforward replacement in existing power stage designs

With a factory lead time of 37 weeks on new production orders, procurement teams relying solely on the factory pipeline face significant exposure to unplanned downtime and project delays. For maintenance engineers managing critical infrastructure or OEMs managing production schedules, sourcing from authorized distributors with available stock is the practical solution. ATI Accurate Technology maintains inventory of high-demand, long-lead-time modules like the CM1200HC-66H precisely to bridge this gap, ensuring your facility or production line is not held hostage to extended manufacturing queues.
