The SEMIKRON SKM600GA125D is a high-performance IGBT power module from the SEMITRANS 4 series, engineered for demanding industrial power conversion applications. Rated at 1200 V and 400 A, it utilizes NPT-IGBT technology featuring a positive temperature coefficient of VCEsat and short-circuit self-limiting protection up to 6 × Ic, ensuring safe and reliable operation. The module complies with IEC 60721-3-3 (humidity) class 3K3 and IEC 68T.1 climate 40/125/56 standards, providing robust environmental resistance. Designed in the SEMITRANS 4 housing format, it measures 106 × 62 × 37 mm and weighs 0.31 kg net (0.42 kg gross). Ideal for resonant inverters up to 100 kHz, inductive heating systems, and electronic welders operating above 20 kHz, the SKM600GA125D delivers high efficiency and thermal stability. In North America, Europe, Asia, and worldwide power electronics industries, this IGBT module may possibly be ideal for systems requiring compact, durable, and high-frequency semiconductor switching solutions.
