Mitsubishi Electric CM400E2U-12F IGBT Power Module

The Mitsubishi Electric CM400E2U-12F IGBT Power Module is a 1200 V, 400 A module engineered for high-efficiency switching in medium- to high-power industrial power systems, commonly used in motor drives, inverters, and power supply assemblies across manufacturing, process control, and HVAC equipment. In an E2U package and designed for direct mounting on a heatsink, it offers a junction-to-case thermal resistance of 0.27°C/W, supports switching up to 20 kHz with low switching losses, and operates from -40°C to 150°C. Its protective features include short-circuit and over-temperature protection, and the unit carries IP20 protection with UL and CE certifications. This module is a suitable replacement option in applications such as HVAC systems, welding equipment, UPS, and other power conversion setups that require reliable, high-speed switching; common replacements include Mitsubishi CM400E2Y-12F, Infineon IKW40N120T2, and Semikron SKM400GB128D.
