  • Data Sheet for 1MBI400U4-120
  • Description

    The 1MBI400U4-120 from Fuji Electric is a high-performance single IGBT module rated at 400 amperes and 1200 volts, engineered for robust industrial power conversion applications. Based on Fuji's proven U4-series IGBT technology, this module delivers excellent switching efficiency, low collector-emitter saturation voltage (VCE(sat)), and reliable thermal performance in a compact package. It is designed to meet the demands of high-frequency, high-power switching circuits where efficiency and durability are paramount.

    The 1MBI400U4-120 is well suited for a broad range of power electronics applications, including three-phase AC motor drives, industrial inverters, uninterruptible power supplies (UPS), servo drive systems, welding equipment, and renewable energy converters such as solar inverters and wind turbine controllers. Its high current and voltage ratings make it a preferred choice in heavy industrial machinery and traction applications where performance under continuous load is critical.
