The Mitsubishi CM400DY-12NF is a high-performance dual (2-in-1) IGBT module from Mitsubishi's NF series, delivering a continuous collector current of 400A at a blocking voltage of 600V (1200V-class designation). Built on advanced NF-series IGBT technology, this module offers low saturation voltage, reduced switching losses, and enhanced thermal performance, making it well-suited for high-efficiency power conversion in demanding industrial environments. The robust package design ensures reliable heat dissipation and long operational life in continuous-duty applications.

The CM400DY-12NF is widely used across a broad range of industrial and commercial power electronics applications. These include AC motor drives and variable frequency drives (VFDs), industrial servo systems, UPS (uninterruptible power supply) systems, solar inverters and wind power converters, induction heating equipment, and DC-DC power converters. Its dual configuration simplifies circuit design and reduces component count in half-bridge and phase-leg topologies.
