The Mitsubishi CM100DU-34KA is a 1700V, 100A IGBT module built in a dual (2-in-1) configuration, making it well suited for demanding high-voltage power conversion circuits. Operating in the upper voltage class of the CM-series lineup, this module features low V_CE(sat) characteristics that reduce conduction losses in high-frequency switching environments. The integrated freewheeling diodes minimize external component count, while the isolated baseplate construction simplifies thermal management in both air-cooled and liquid-cooled heatsink assemblies. Engineers specifying parts for 690V AC bus topologies routinely select this module for its balance of switching speed and ruggedness.

The CM100DU-34KA sees widespread use across heavy industrial and renewable energy platforms. Typical applications include medium-voltage variable frequency drives (VFDs), regenerative elevator drives, traction inverters, high-power UPS systems, induction heating equipment, and wind turbine converter stages. Its 1700V blocking capability provides the necessary voltage headroom when operating on 690V or 1000V DC-link buses, and the 100A continuous current rating supports multi-kilowatt load profiles without derating in properly heatsinked enclosures. Any application demanding reliable switching at the upper end of the standard industrial voltage range is a strong candidate for this device.

Key Features of the CM100DU-34KA:

• 1700V V_CES blocking voltage with 100A continuous collector current rating for high-power, high-voltage converter topologies
• Dual (2-in-1) IGBT configuration with integrated anti-parallel freewheeling diodes, reducing external component count and PCB footprint
• Low V_CE(sat) for reduced on-state conduction losses, improving overall converter efficiency at rated current
• Short-circuit withstand capability supporting fault-tolerant gate drive designs in safety-critical industrial systems
• Isolated copper baseplate construction enabling direct mounting to standard heatsinks with controlled clamping torque for optimized thermal resistance
• Compatible with standard Mitsubishi CM-series footprint, simplifying drop-in replacement during maintenance or system upgrades

With a factory lead time of 33 weeks for new production, the CM100DU-34KA presents a significant procurement challenge for operations that cannot afford extended downtime or project delays. Mitsubishi's higher-voltage IGBT modules in this current class are consistently in tight supply globally, and allocation windows can shift with little notice. ATI Accurate Technology maintains independent stock of hard-to-find and long-lead-time power semiconductors precisely for these situations, giving maintenance teams and procurement professionals access to critical inventory without waiting on factory queues or navigating broker uncertainty.
