CM300EXS-24S Mitsubishi - IGBT Module

CM300EXS-24S Description

CM300EXS-24S is a 1,200 V / 300 A single-switch (brake chopper) IGBT module from Mitsubishi Electric, S series (6th generation IGBT). Datasheet ratings: 300 A DC at TC = 119 °C, VCE(sat) 1.80 V typ. at 300 A, 4,000 V RMS isolation. Typical applications: Brake. Mitsubishi lists it as not recommended for new design and names the NX-type T/T1 series as the alternative.
