The Mitsubishi CM300DY-24NFH is a 300A, 1200V dual (two-in-one) IGBT module belonging to Mitsubishi's high-performance NFH series. Housed in a standard Mitsubishi power module package, this device integrates two IGBT chips with freewheeling diodes in a common-emitter half-bridge configuration. The NFH-series design emphasizes reduced switching losses, low V_CE(sat), and enhanced thermal cycling endurance, making it a reliable choice for demanding power conversion environments where efficiency and long operational life are non-negotiable requirements.

The CM300DY-24NFH is widely deployed in industrial AC motor drives, servo amplifiers, regenerative inverters, induction heating systems, and large UPS installations. Its 1200V blocking voltage and 300A continuous current rating make it well-suited for 690VAC bus architectures and medium-voltage drive platforms. OEM machine builders, panel integrators, and industrial MRO teams frequently specify this module in equipment serving steel mills, paper mills, HVAC systems, crane and hoist drives, and grid-tied energy storage inverters.

Key Features of the CM300DY-24NFH:

• 1200V V_CES rating provides adequate voltage margin for 690VAC three-phase drive topologies with standard derating practices
• 300A continuous collector current supports high-torque, low-speed operation in heavy industrial drive applications
• Low V_CE(sat) characteristic reduces on-state conduction losses, improving inverter efficiency across the load range
• Integrated co-pack freewheeling diodes with optimized reverse recovery characteristics minimize switching transients and EMI
• NFH-series package offers enhanced power cycling capability, critical for applications with frequent start/stop or variable load profiles
• Isolated baseplate construction simplifies thermal management and heatsink mounting in multi-module inverter assemblies

With a factory lead time of 34 weeks for new production, procurement teams relying solely on the factory pipeline risk costly downtime during emergency replacements or unexpected failures. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time IGBT modules precisely to bridge this gap. Whether you are supporting a capital repair, building safety stock for critical machinery, or responding to an unplanned outage, having a distributor with physical inventory of the CM300DY-24NFH eliminates the uncertainty of a multi-month factory queue and keeps your production assets running.

ATI Accurate Technology is located in Palmetto, Florida, and stocks the CM300DY-24NFH as new OEM product ready for immediate shipment. Orders placed before 5PM EST ship same day. ATI serves maintenance engineers, OEM service departments, and procurement professionals with competitive pricing, volume discounts, and responsive technical support.
