The CM300HA-24H is a Mitsubishi high-current IGBT module rated at 300 amperes and 1200 volts, built for high-frequency switching in industrial power conversion systems. This module integrates an IGBT and free-wheeling diode in a single package, offering low collector-emitter saturation voltage (V_CE(sat)) and fast switching characteristics. Its robust construction is engineered to withstand the thermal and electrical stresses of continuous duty operation, making it a reliable choice for engineers specifying components in demanding power electronics platforms where performance consistency and longevity are non-negotiable.

The CM300HA-24H sees widespread deployment across industrial AC and DC motor drives, regenerative converters, UPS systems, induction heating equipment, and welding power supplies. Its 1200V blocking voltage and 300A current rating position it squarely in medium-to-high power inverter stages where bus voltages in the 600–800V range are standard. It is also commonly found in traction drives, crane and hoist controls, and industrial servo amplifiers where thermal reliability and switching efficiency directly impact system uptime and energy consumption.

Key Features of the CM300HA-24H:

• 1200V collector-emitter voltage (V_CEO) with 300A continuous collector current rating for high-power inverter stages
• Integrated free-wheeling diode co-packaged with the IGBT for simplified circuit design and reduced parasitic inductance
• Low V_CE(sat) characteristic minimizes on-state conduction losses and reduces heatsink thermal requirements
• Optimized gate charge and switching speed balance switching losses against EMI in PWM inverter applications
• Industry-standard module footprint compatible with common Mitsubishi HA-series mounting hardware and gate driver platforms
• Isolated baseplate construction supports direct mounting to water-cooled or forced-air heatsinks for flexible thermal management

With a factory lead time of 38 weeks on new production, the CM300HA-24H presents a real procurement challenge for facilities running scheduled maintenance programs or managing unplanned equipment failures. Mitsubishi IGBT modules of this class are frequently specified in legacy drive platforms that remain in service well beyond original design life, and finding certified new OEM stock through distribution channels is increasingly difficult. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time IGBT modules precisely to bridge this gap, helping maintenance and procurement teams avoid extended equipment downtime caused by component availability constraints.

ATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts.
