Fuji 2MBI300N-120 IGBT Module | High-Current Power Switching for Demanding Applications
Product Overview
The Fuji 2MBI300N-120 is a high-performance 1200V, 300A N-channel IGBT module, engineered in a versatile half-bridge (2-in-1) configuration. Designed for high-power conversion systems, this module provides a robust and reliable solution for applications such as large-scale industrial motor drives, high-capacity uninterruptible power supplies (UPS), and renewable energy inverters. The Fuji 2MBI300N-120 excels in environments where efficient and stable power control is not just a feature, but a critical operational requirement.
Core Product Features In-Depth Analysis
Low Conduction Loss via Low Vce(sat)
- Technical Principle: This module leverages Fuji Electric's mature N-series trench-gate and field-stop (FS) IGBT technology. This sophisticated silicon design significantly reduces the on-state voltage drop, achieving a typical Vce(sat) of just 2.2V at its nominal 300A rating.
- Application Value: Lower Vce(sat) directly translates to reduced conduction losses—the primary source of heat in high-current applications. For system designers, this means less thermal stress on the component, enabling the use of smaller, more cost-effective heatsinks. The result is a more compact, reliable, and energy-efficient system, especially critical in continuous-duty applications like industrial motor drives.
Optimized Switching Performance with Soft-Recovery FWD
- Technical Principle: The 2MBI300N-120 is engineered for fast, clean switching characteristics. It incorporates a co-packaged Free Wheeling Diode (FWD) optimized for soft and rapid reverse recovery. This combination, along with a low-inductance internal package design, minimizes voltage overshoots and ringing during high-frequency switching events.
- Application Value: This feature is invaluable for applications like high-frequency welding equipment and solar inverters. The controlled switching behavior reduces electromagnetic interference (EMI), simplifying the design and cost of filtering circuitry. The soft-recovery diode mitigates high-frequency oscillations, which improves overall system stability and reduces stress on other components, leading to a longer operational lifespan.
Typical Application Scenarios & Value Proposition
- Industrial Motor Drives and Inverters: The module's 300A current capability is ideal for controlling large AC motors in manufacturing, HVAC, and pumping systems. Its low thermal losses ensure stable operation under heavy loads, improving motor efficiency and reducing system downtime for maintenance.
- Uninterruptible Power Supplies (UPS): In data centers and critical facilities, the reliability of the Fuji 2MBI300N-120 is paramount. Its 1200V breakdown voltage provides a robust safety margin against grid transients, while its high efficiency in the inverter stage maximizes battery runtime during a power outage.
- Welding Equipment: The fast and clean switching enables the design of compact, lightweight inverter-based welders. This allows for superior arc stability and control, resulting in higher-quality welds and increased productivity compared to older, transformer-based technologies.
- Solar & Wind Energy Inverters: Maximizing energy harvest is the goal. The low switching and conduction losses of this IGBT module ensure that a greater percentage of the DC power generated by solar panels or wind turbines is successfully converted into usable grid-tied AC power, directly improving the financial return of the renewable energy system.

Product Comparison & Selection Advice
When evaluating power modules, engineers often compare devices like the Fuji 2MBI300N-120 with newer-generation modules. While newer series (like Fuji’s V-Series) may offer slightly lower Vce(sat) and faster switching for cutting-edge efficiency, the N-Series stands out as a proven, highly robust, and cost-effective solution. For applications operating at moderate switching frequencies (up to ~20 kHz) where long-term reliability and a balanced performance-to-cost ratio are the primary drivers—such as in standard industrial inverters and UPS systems—the 2MBI300N-120 remains a superior engineering choice. If your design prioritizes field-proven ruggedness over achieving the absolute peak in power density, this module delivers exceptional value.
