The Mitsubishi CM100DU-12H is an industry-proven Dual IGBT module engineered for performance, efficiency, and long-term reliability in demanding power electronics applications. Combining a 600V blocking voltage with a 100A continuous current rating, this module serves as a fundamental building block for designers of inverters, motor drives, and power supplies who require a balance of robust performance and thermal efficiency in a compact, integrated package.
Product Highlights Overview
As a key component in Mitsubishi's H-Series family, the CM100DU-12H delivers a potent combination of features optimized for real-world engineering challenges:
- Voltage and Current Rating: 600V / 100A, ideal for systems operating from 200-240V AC lines.
- Configuration: Dual (Half-Bridge) topology, simplifying the design of 2-level inverters and DC-DC converters.
- Core Technology: Features Mitsubishi's 4th generation CSTBT™ (Carrier Stored Trench-gate Bipolar Transistor) technology for an optimized balance between conduction and switching losses.
- Integrated Diode: Includes a co-packaged, fast and soft recovery free-wheeling diode (FWD) for superior performance in inductive switching applications.
- Isolation: Provides 2500V (RMS) of isolation between the terminals and the baseplate, ensuring safety and simplifying system assembly.
Technical Deep Dive: CSTBT™ and Half-Bridge Advantage
The performance of the CM100DU-12H is rooted in its sophisticated silicon design and intelligent packaging. Two aspects are particularly critical for design engineers:
1. Fourth-Generation CSTBT™ Technology: Unlike standard planar or trench IGBTs, Mitsubishi's CSTBT™ incorporates a unique carrier storage layer beneath the trench gate. This engineering feat allows the device to achieve a low on-state voltage drop (VCE(sat)) without the typical penalty of dramatically increased switching energy (Eoff). For the designer, this translates directly into lower overall power loss, reducing heatsink requirements and improving system efficiency, especially in applications with moderate to high switching frequencies.
2. Integrated Half-Bridge Configuration: The "DU" designation signifies a dual IGBT configuration, forming a complete half-bridge leg in a single module. This integration offers significant advantages over using two discrete IGBTs. It minimizes the stray inductance in the critical commutation loop between the high-side and low-side switches. This reduction in parasitic inductance lowers voltage overshoots during turn-off, enhancing device reliability and often simplifying or eliminating the need for complex snubber circuits. Furthermore, co-locating the two IGBTs and diodes on a single insulated metal substrate ensures superior thermal tracking and more effective heat dissipation.
