Mitsubishi CM200DY-12H | A Workhorse IGBT for High-Reliability Power Conversion
The Mitsubishi CM200DY-12H is not just another power semiconductor; it's an engineering staple for high-power applications where reliability and performance are non-negotiable. This 1200V, 200A dual IGBT module represents a legacy of robust design, offering a proven solution for engineers developing demanding power conversion systems. Its H-Series technology is specifically engineered for an optimal balance between conduction losses, switching speed, and ruggedness.
- Voltage and Current Rating: 1200V / 200A, providing substantial headroom for industrial-grade applications.
- Topology: Dual IGBT (Half-Bridge) configuration, ideal for simplifying inverter and chopper circuit designs.
- Core Technology: Built upon Mitsubishi's established planar cell structure, optimized for low VCE(sat) and robust short-circuit withstand capability.

Application Scenarios & Engineering Value
The true value of the CM200DY-12H is demonstrated in its performance within specific, demanding environments. Its design characteristics directly address common engineering challenges.
- Industrial Motor Drives: In Variable Frequency Drive (VFD) applications, the low collector-emitter saturation voltage (VCE(sat)) is paramount. It directly reduces conduction losses, which are often the dominant loss factor at the typical operating frequencies of motor control. This translates to higher system efficiency, reduced heatsink requirements, and lower operational temperatures, enhancing the lifespan of the entire drive.
- Uninterruptible Power Supplies (UPS): For mission-critical UPS systems, reliability is the primary design driver. The CM200DY-12H's proven field performance and high short-circuit withstand time (SCSOA) provide the robustness needed to handle grid anomalies and load faults without catastrophic failure, ensuring continuous, clean power.
- Welding Power Supplies: The pulsed, high-current nature of welding demands a component that can endure significant electrical and thermal stress. This module's excellent thermal cycling capability and rugged internal construction make it a premier choice for both inverter-based stick and MIG welding systems.
Technical Deep Dive: The Engineering Behind the Specs
Two key aspects define the CM200DY-12H's performance profile: its balanced loss characteristics and its thermal design.
Firstly, this module is a masterclass in compromise engineering. While some modern devices chase ultra-fast switching speeds at the cost of higher on-state voltage, the H-series was optimized for the moderate frequency range (2-15 kHz). By prioritizing a low VCE(sat), Mitsubishi ensures that in applications where the device spends a significant portion of its cycle conducting current, overall power dissipation is minimized. This design choice simplifies thermal management and often leads to a more cost-effective total system.
Secondly, the module's construction is built for longevity. The use of an isolated copper baseplate provides a low thermal resistance path from the semiconductor die to the heatsink. This efficient heat extraction is critical for preventing device degradation and is a key factor in the module's impressive power cycling capability.

Frequently Asked Questions (FAQ)
1. What are the key considerations for the gate drive circuit for the CM200DY-12H?
A robust gate drive is critical. We recommend a dual-supply voltage of +15V for turn-on and -10V to -15V for turn-off. The negative turn-off voltage is essential to provide a strong buffer against dV/dt induced turn-on (Miller effect), particularly crucial in the half-bridge topology to prevent shoot-through. For more on this topic, explore our 5 practical tips for robust gate drive design.
2. Is the CM200DY-12H suitable for paralleling to achieve higher current?
Yes, these modules can be paralleled effectively. A key advantage is the positive temperature coefficient of VCE(sat), which naturally helps balance current sharing between modules as they heat up. However, successful paralleling requires careful attention to symmetrical PCB layout to equalize stray inductances and the use of individual gate resistors for each module to dampen potential oscillations.
Strategic Advantage: Prioritizing Proven Reliability
In an industry often focused on the newest technology, the Mitsubishi CM200DY-12H holds a unique strategic position. It is the definitive choice for systems where the Total Cost of Ownership (TCO)—factoring in initial cost, development time, and long-term field reliability—is the primary metric. For engineers designing systems that will be deployed for a decade or more in harsh industrial environments, the proven track record of this IGBT module provides a level of design assurance and risk mitigation that newer, less-established technologies cannot yet match.
