The Mitsubishi CM50DU-24H is a 50-ampere, 1200-volt dual IGBT module engineered for high-efficiency power switching in industrial and commercial power electronics systems. Built on Mitsubishi's proven IGBT chip technology, this module integrates co-pack freewheeling diodes, delivering low collector-emitter saturation voltage (V_CE(sat)) and controlled switching characteristics that minimize thermal stress and switching losses. Its robust isolated baseplate construction supports reliable thermal management in demanding environments, making it a dependable solution for design engineers and maintenance professionals requiring consistent gate performance and long service life.

The CM50DU-24H is well-suited for a broad range of industrial applications including variable frequency drives (VFDs), AC and DC motor controllers, uninterruptible power supplies (UPS), induction heating systems, welding inverters, and servo amplifiers. Its 1200V blocking voltage provides adequate headroom for 480VAC three-phase bus architectures, while the 50A current rating accommodates mid-range power stages where switching efficiency and thermal reliability are paramount. OEMs and field service teams across industries such as manufacturing automation, renewable energy, and material handling routinely specify this module in both new designs and replacement scenarios.

Quick Reference: CM50DU-24H

Key Features of the CM50DU-24H:

• 1200V collector-emitter breakdown voltage (V_CES) suitable for 480VAC three-phase power bus applications with standard derating margins
• 50A continuous collector current rating with integrated co-pack freewheeling diodes for simplified circuit design and reduced component count
• Low V_CE(sat) for reduced conduction losses and improved thermal efficiency across the full operating duty cycle
• Isolated copper baseplate for direct heatsink mounting, supporting effective thermal dissipation in high-duty-cycle switching applications
• Dual (2-in-1) module configuration simplifies half-bridge leg construction in inverter and converter topologies
• Industry-standard footprint and pinout compatible with common Mitsubishi DU-series mounting arrangements, facilitating drop-in replacement

With a factory lead time of 39 weeks on new production, the CM50DU-24H presents a serious procurement challenge for maintenance teams dealing with unplanned equipment failures or production line downtime. End-of-life and long-lead IGBT modules like this one are precisely where distributor inventory becomes operationally critical. Whether you're maintaining legacy drives, supporting installed base equipment past its production window, or managing a capital spares program, waiting on factory allocation is rarely an acceptable option. ATI's in-stock position on the CM50DU-24H eliminates that risk and gets your equipment back online without a 9-month delay.
