The Mitsubishi CM300HA-12H is a 1200V, 300A IGBT module engineered for high-current switching in industrial power electronics. Part of Mitsubishi's proven HA-series line, this module integrates insulated gate bipolar transistor technology with a freewheeling diode in a rugged, isolated-base package. It is optimized for low saturation voltage and controlled switching losses, making it well suited for continuous-duty inverter and converter topologies where thermal stability and long service life are non-negotiable requirements for maintenance and design engineers alike.

The CM300HA-12H sees wide deployment across industrial variable frequency drives (VFDs), servo amplifiers, UPS systems, induction heating equipment, and medium-voltage DC bus converters. Its 1200V blocking capability provides the headroom required in 480–690VAC three-phase input systems, while the 300A current rating supports multi-kilowatt motor drive stages and active front-end rectifier designs. It is also found in traction auxiliary converters, welding inverters, and renewable energy power conditioning systems where switching reliability under thermally stressful cycles is paramount.

Quick Reference: CM300HA-12H

Key Features of the CM300HA-12H:

• 1200V collector-emitter voltage (VCES) with 300A continuous collector current rating for high-power inverter stages
• Low VCE(sat) characteristics reduce conduction losses and minimize heat sink thermal load in continuous-duty cycles
• Integrated freewheeling diode optimized for recovery characteristics compatible with high-frequency PWM switching
• Isolated copper base plate construction enables direct mounting to heat sinks with standard thermal interface materials
• Gate drive compatible with industry-standard IGBT driver ICs and isolated gate driver modules at ±15V bias
• Industry-standard module footprint simplifies direct replacement in existing PCB and busbar-connected drive platforms

With a factory lead time of 99 weeks on new production, procurement teams relying solely on the manufacturer's supply chain face serious risk of extended equipment downtime or delayed project schedules. The CM300HA-12H is a well-established part with a large installed base across global industrial infrastructure, meaning demand for spares and replacements consistently outpaces available stock from standard distribution channels. Securing verified new OEM inventory from a specialized stocking distributor is the most effective strategy for maintaining uptime and meeting project deadlines without compromise on part authenticity or quality.
