Semikron Danfoss SKM75GB12T4 1200V, 75A IGBT Module

SKM75GB12T4 IGBT Module

The SKM75GB12T4 is a half-bridge IGBT module built for demanding power electronics applications. With a rating of 1200 V and nominal current around 75 A (continuous current up to ~115 A under certain conditions), this module combines high power handling with excellent electrical and thermal performance. It is especially suitable for industrial and commercial use, including AC inverter drives, UPS systems, and electronic welding equipment, where efficiency and durability are essential.

Reliability is enhanced via modern IGBT4 (fourth generation trench IGBT) chip technology, a CAL4 soft‐switching diode, and a copper baseplate with DBC (Direct Bonded Copper) construction. The module supports high switching frequencies (up to about 20 kHz), has good power cycling capability, and includes an integrated gate resistor that helps reduce switching losses and improve system stability. These features make it durable under thermal cycling, capable of withstanding high junction temperatures (up to 175 °C) while maintaining low saturation voltage and stable performance.

SKM75GB12T4 delivers benefits such as high efficiency (thanks to low VCE(sat) and CAL4 diode soft recovery), robust performance in harsh environments, and reduced need for maintenance due to its solid design. It is suitable for both industrial settings (motors, inverters) and commercial equipment (UPS, welding, large power supplies). For full technical details, please refer to the datasheet.
