The Mitsubishi CM450DY-24S is a 450A, 1200V dual IGBT module engineered for high-power industrial and power conversion applications where reliability and switching performance are non-negotiable. Built on Mitsubishi's proven IGBT technology, this module integrates freewheeling diodes and features low saturation voltage (V_CE(sat)) characteristics that minimize conduction losses across a wide load range. Its robust isolated base plate construction supports effective thermal management when properly mounted to an appropriate heatsink, making it a dependable choice for demanding continuous-duty environments.

The CM450DY-24S is widely deployed in AC and DC motor drives, regenerative braking systems, UPS inverters, induction heating equipment, and industrial servo amplifiers. It is also found in rail traction auxiliaries, large-scale solar inverters, and medium-voltage power supplies where high current handling and voltage blocking capability are essential. Engineers specifying this module benefit from its balance of switching speed and conduction loss — a critical trade-off in high-frequency PWM drive topologies operating at the kilowatt to megawatt scale.

Key Features of the CM450DY-24S:

• 1200V collector-emitter voltage (V_CES) with 450A continuous collector current rating for high-power density applications
• Dual (chopper) configuration with integrated antiparallel freewheeling diodes for simplified inverter leg design
• Low V_CE(sat) for reduced on-state conduction losses in high duty-cycle and continuous-load scenarios
• Isolated copper base plate construction enables direct mounting to heatsink with standard thermal interface materials
• Optimized gate drive characteristics compatible with standard IGBT gate driver ICs and isolated driver modules
• Designed for PWM switching frequencies typical of industrial variable frequency drives and precision servo systems

With a factory lead time of 32 weeks on new production, procurement teams and MRO buyers sourcing the CM450DY-24S for emergency repairs, scheduled maintenance, or production line continuity face serious exposure to costly downtime. Mitsubishi IGBT modules in the CM-series 1200V range are consistently among the highest-demand, longest lead-time parts in the industrial power electronics market. Whether you're replacing a failed module in a live drive system or building safety stock ahead of a planned outage, waiting on factory delivery is rarely an acceptable option.
