  • Data Sheet for 1MBI400S-120
  • Description

    The 1MBI400S-120 is a robust single IGBT module manufactured by Fuji Electric, rated for 400 amperes and 1200 volts. Built on Fuji's proven IGBT technology, this module delivers low collector-emitter saturation voltage (VCE(sat)) and excellent switching efficiency, making it a preferred choice for high-current industrial power electronics. The rugged package construction ensures reliable thermal performance and long operational life even under continuous heavy-load conditions.

    This module is well-suited for a wide range of power conversion and motor control applications including industrial AC motor drives, three-phase inverters, uninterruptible power supply (UPS) systems, induction heating equipment, welding machines, and traction drives. Its high current rating and 1200V blocking capability make it especially valuable in medium-voltage industrial infrastructure where reliability and efficiency are paramount.
