Mitsubishi CM200DY-34A | Robust 1700V Dual IGBT for High-Power Industrial Applications
The Mitsubishi CM200DY-34A is a high-reliability dual IGBT module engineered for the rigorous demands of modern power conversion systems. With its 1700V blocking voltage and 200A current rating, this A-Series module provides a proven, robust solution for applications where performance and long-term durability are non-negotiable. It is the go-to component for designers of high-power industrial motor drives, large-scale uninterruptible power supplies (UPS), and general-purpose inverters that require exceptional operational stability.
Engineering Excellence: A Closer Look at Core Technology
Optimized for Low Conduction Losses (Low Vce(sat))
Technical Principle: The CM200DY-34A is designed with a focus on minimizing the collector-emitter saturation voltage (Vce(sat)). This parameter is a direct measure of the power lost as heat when the IGBT is in its 'on' state. Mitsubishi's mature planar cell structure and carrier lifetime control technologies ensure this voltage remains exceptionally low under heavy load conditions.
Application Value: For an engineer, a lower Vce(sat) translates directly into higher system efficiency. This reduces operational energy costs over the equipment's lifecycle and, critically, lessens the thermal burden. The result is the ability to design more compact, cost-effective cooling systems (heatsinks) and improve the overall power density of the final product.
Superior Free-Wheeling Diode (FWD) Characteristics
Technical Principle: Integrated within the module is a free-wheeling diode optimized for soft and fast recovery. When the IGBT switches off, this diode must handle the inductive load current. A "soft" recovery characteristic prevents large voltage spikes (overshoots) and reduces high-frequency ringing.
Application Value: This seemingly small detail has a massive impact on system reliability and design complexity. The soft recovery of the FWD in the CM200DY-34A significantly simplifies electromagnetic compatibility (EMC) design, reducing the need for bulky and expensive snubber circuits. It mitigates voltage stress on the IGBT, directly contributing to a longer operational lifespan and a more resilient power stage.
Application Value Across Demanding Industries
- Heavy-Duty Motor Drives: In applications like industrial cranes, elevators, and large conveyor systems running on 690V AC lines, the 1700V rating of the CM200DY-34A provides a critical safety margin. Its robust thermal performance ensures reliable operation even during high-torque, low-speed maneuvers that stress power electronics.
- Uninterruptible Power Supplies (UPS): For data centers and critical facilities, system uptime is paramount. The proven reliability and low failure rate of Mitsubishi's A-Series modules make the CM200DY-34A an ideal choice for the inverter stage of high-capacity UPS systems, ensuring a stable power supply when it matters most.
- Industrial Power Converters & Inverters: The dual-IGBT configuration (two switches in one package) is perfect for building the legs of a three-phase inverter bridge. Using three CM200DY-34A modules simplifies the mechanical layout, reduces component count, and streamlines the assembly process for general-purpose inverters.

Selection Guidance: CM200DY-34A vs. Newer Technologies
While newer IGBT generations may offer faster switching speeds, the Mitsubishi CM200DY-34A holds a distinct advantage in low-to-medium frequency applications (< 10kHz) where ruggedness and low conduction losses are the primary design drivers. For systems like large motor drives, its performance-to-cost ratio and proven field reliability are often superior to more specialized, higher-frequency modules. If your design prioritizes ultimate efficiency at higher switching frequencies (e.g., in solar inverters or welding equipment), you may want to explore newer trench-gate or SiC-based solutions.

Frequently Asked Questions
- Can the CM200DY-34A modules be connected in parallel for higher current?Yes, paralleling is possible. However, it requires careful attention to gate drive signal symmetry and a balanced power layout to ensure proper current sharing between the modules. We recommend consulting the application notes or our technical team for best practices.
- What is the typical gate drive voltage for this module?The recommended gate drive voltage is typically +15V for turning the IGBT on and -10V to -15V for a secure turn-off, ensuring high immunity against parasitic turn-on.
- Why choose a 1700V module for a 690V AC system?Using a 1700V rated module on a 690V AC line provides a substantial safety margin. It comfortably handles the DC bus voltage (approx. 975V) plus any voltage overshoots caused by stray inductance during switching, which is crucial for long-term system reliability.
