M2. Introduction & Core Specifications
A Strategic Blend of Conduction and Switching Performance
The Fuji Electric 2MBI200UC-120 is a 1200V dual IGBT module engineered to provide a robust and balanced performance for high-frequency power conversion systems. It offers a cost-effective equilibrium between conduction and switching losses, a critical requirement for designers optimizing system efficiency and thermal stability. Delivering key specifications of 1200V | 200A | VCE(sat) of 2.7V (typ.), this U-series module provides two primary engineering benefits: predictable thermal behavior and reliable switching characteristics.

B2. Application Scenarios & Value
Enhancing Performance and Reliability in Industrial Motor Drives
The 2MBI200UC-120 is particularly well-suited for integration into medium-power Variable Frequency Drives (VFDs), AC servo drives, and general-purpose inverters. A primary engineering challenge in these applications is managing the trade-off between heat generated during full-load operation (conduction losses) and heat generated during transistor switching (switching losses). The module's typical Collector-Emitter Saturation Voltage (VCE(sat)) of 2.7V directly impacts conduction losses. Think of VCE(sat) as the toll a current pays to pass through the device; a lower toll means less energy is wasted as heat when the motor is running steadily. Simultaneously, its defined turn-on (Eon) and turn-off (Eoff) energies ensure that switching losses are controlled and predictable, which is vital for systems employing high-frequency Pulse Width Modulation (PWM) to achieve smooth motor control. This balance allows designers to specify smaller heatsinks, reduce system costs, and improve overall reliability by minimizing thermal stress on the component and surrounding electronics. For systems requiring higher current capacity within a similar voltage class, the 2MBI300HH-120 offers an increased current rating for more demanding applications.
B7. FAQ
Engineering Questions on Implementation and Performance
How does the VCE(sat) of 2.7V influence the thermal design for a 100kW motor drive?
A VCE(sat) of 2.7V at 200A translates to approximately 540W of conduction loss per switch at full load. This figure is a critical input for thermal simulation. It allows an engineer to accurately calculate the required heatsink performance (thermal resistance) to keep the junction temperature below the 150°C maximum, ensuring the system operates within its Safe Operating Area (SOA) and achieves its target operational lifespan.
What is the primary benefit of this module's U-Series technology?
The key benefit is its balanced loss characteristic, making it a versatile and cost-effective choice for applications with switching frequencies typically in the 5 to 15 kHz range without requiring more advanced, expensive technologies.
