  • Data Sheet for 6MBI300U4-120
  • Description

    The 6MBI300U4-120 is a high-performance 6-in-1 IGBT module from Fuji Electric, rated at 300 amperes and 1200 volts. Built on Fuji's proven U4-series (4th generation) IGBT platform, this module integrates six IGBT chips with freewheeling diodes in a single housing, enabling a complete three-phase inverter bridge in one compact package. Its advanced trench-gate technology delivers reduced conduction and switching losses, making it a preferred choice for demanding power conversion applications.

    The 6MBI300U4-120 is widely used across a broad range of industrial and commercial power electronics applications, including AC motor drives and variable frequency drives (VFDs), industrial servo systems and CNC machine tool controllers, uninterruptible power supplies (UPS), solar and renewable energy inverters, and welding power supplies. Its rugged construction and thermal performance make it suitable for continuous-duty industrial environments where reliability is paramount.
