Fuji Electric 6MBI100S-120-52 | Optimized 6-pack IGBT for High-Efficiency Inverters
The Fuji Electric 6MBI100S-120-52 is a testament to refined power electronics engineering, offering a robust 6-pack IGBT module configuration in a compact, industry-standard package. This 1200V, 100A module is not just a collection of switches; it is a highly integrated solution engineered for designers of motor drives, uninterruptible power supplies (UPS), and other demanding power conversion systems who prioritize efficiency, thermal stability, and long-term reliability. By integrating Fuji's advanced V-Series trench gate field-stop technology, the 6MBI100S-120-52 directly addresses the critical challenge of minimizing power losses without compromising on ruggedness.
Technical Deep Dive: The Core of Performance
Two key technological advancements define the superior performance of the Fuji Electric 6MBI100S-120-52, translating directly into tangible system-level benefits.
- Significantly Reduced Vce(sat): This module features an exceptionally low collector-emitter saturation voltage (Vce(sat)). This is achieved through an optimized V-Series trench gate structure and a fine-tuned field-stop layer. Application Value: For your design, this means a direct reduction in conduction losses—the primary source of heat in many inverter applications. The result is a cooler-running system, which simplifies thermal management, allows for smaller heatsinks, and ultimately enhances the overall operational efficiency and lifetime of the end product.
- Soft & Fast Recovery FWD: Each IGBT is paired with an optimized Free-Wheeling Diode (FWD) engineered for soft recovery characteristics. This design minimizes voltage overshoot and ringing during the diode's turn-off phase. Application Value: This "soft" behavior significantly reduces electromagnetic interference (EMI). Engineers can therefore simplify or even eliminate complex snubber circuits and reduce the size of EMI filters, leading to lower component count, reduced PCB complexity, and faster time-to-market.
Multi-Dimensional Application Scenarios & Value
The technical strengths of the 6MBI100S-120-52 translate into specific advantages across various industrial applications:
- Variable Frequency Drives (VFDs): In industrial motor control, efficiency is paramount. The low Vce(sat) of this IGBT module reduces wasted energy, leading to tangible operational cost savings over the drive's lifespan. Its thermal stability ensures reliable performance even under heavy, continuous loads.
- Uninterruptible Power Supplies (UPS): For critical power systems, every watt counts. The high efficiency of the 6MBI100S-120-52 maximizes battery runtime during outages and lowers the thermal load in data centers or server rooms, reducing cooling costs.
- Servo Drives & Robotics: Precision and speed are non-negotiable. The module's fast switching capabilities and low losses enable the rapid and accurate current control required for high-performance motion control systems, ensuring precise positioning and smooth operation.
- Industrial Welding Equipment: Welding applications impose harsh, pulsed current demands. The robust thermal design and rugged chip technology of the Fuji Electric 6MBI100S-120-52 ensure it can withstand these punishing cycles, delivering consistent power for high-quality welds.

Selection Advice & Competitive Comparison
When evaluating options, engineers might compare the Fuji Electric 6MBI100S-120-52 with older-generation modules or competitor parts. Compared to Fuji's previous U4-Series, the V-Series chip in the -52 version offers a superior trade-off between Vce(sat) and switching speed, making it ideal for applications operating in the 5-20 kHz range. While dedicated high-frequency modules might offer lower switching losses, they often do so at the cost of higher conduction losses. The 6MBI100S-120-52 hits a sweet spot, providing exceptional performance for the majority of industrial inverter applications where both loss mechanisms are critical. For new designs requiring a balance of efficiency and cost-effectiveness, this module is a clear upgrade path. To review our full range of solutions, explore more IGBT Modules on our website.
Frequently Asked Questions (FAQ)
- What does the "-52" suffix indicate?
The "-52" suffix in Fuji Electric modules typically designates their advanced V-Series IGBT technology. This series is specifically optimized for low conduction losses (Vce(sat)) and improved thermal performance, representing a significant step up from older generations. - Can the 6MBI100S-120-52 modules be paralleled for higher current?
Yes, these modules can be paralleled. However, successful paralleling requires careful attention to symmetrical PCB layout to equalize stray inductances, as well as matching gate drive circuits and potentially using individual gate resistors to ensure balanced current sharing during switching transients. - What are the recommended gate drive conditions?
For optimal performance and to ensure full saturation and secure turn-off, a gate drive voltage of +15V for turn-on and -15V (or -8V to -15V) for turn-off is recommended. A negative gate voltage is crucial for improving noise immunity and preventing parasitic turn-on.
