The CM400DY-24NF is a high-power switching IGBT module manufactured by Powerex Inc. It features an N-channel configuration with a maximum collector-emitter voltage of 1200 V and a continuous collector current rating of 400 A. The device utilizes a flange mount package design for efficient thermal management. Internally, it integrates two elements in a series-connected, center-tapped configuration with built-in diodes. The module is designed for robust performance in demanding power electronics applications.
Verify the manufacturer designation carefully, as this component is historically associated with Mitsubishi Electric Semiconductor. Confirm that the supplied unit matches the specific CM400DY-24NF part number and physical dimensions. Ensure the packaging condition meets storage requirements for sensitive semiconductor devices prior to installation.
Select this module when a 1200 V, 400 A rated insulated IGBT is required. Consider the flange mount style for mechanical stability and thermal conductivity. Verify that the application circuit supports the series-connected, center-tapped internal topology. Ensure adequate gate drive capabilities are available for the specified current levels.
This component belongs to the family of high-power IGBT modules designed for industrial switching applications. Similar variants include the CM600DU-24NFH and CM300DY-24NF, which offer different current ratings within the same voltage class. These modules are typically used in medium to high-power conversion systems requiring reliable semiconductor switching.
Direct substitutes may include the CM300DY-24NF or CM600DU-24NFH depending on current requirements. Verify pin compatibility and thermal resistance characteristics before substitution. Cross-reference with Mitsubishi Electric Semiconductor datasheets for equivalent specifications.
