The Semikron SKM150GB12T4 is a IGBT module rated 150 A at 1200 V, supplied in the SEMITRANS 2 housing.
IGBT modules are the power switches of inverter drives, UPS systems, welders and converters: they switch the DC-link voltage to build the motor or output current, so a failed module is one of the most common causes of a drive fault.

Compatibility and replacement
Order with the complete Semikron type SKM150GB12T4; in Semikron type codes the digits and letters set the current, voltage class, topology and chip generation, so a module with a similar number may not be a direct replacement.
The values in the table come from the official Semikron Danfoss product data; for full electrical ratings (VCE(sat), switching losses, thermal resistance) we send the datasheet with the quotation.
Replacement checklist
- Voltage class (1200 V or 1700 V) and current rating
- Gate driver compatibility and thermal paste / mounting torque
- Housing (SEMITRANS 2/3, SEMiX) and terminal layout
Frequently asked questions
Should the gate driver be checked when the module failed?
Yes. A failed IGBT often damages the gate driver as well; check the driver, the DC-link capacitors and the thermal paste before fitting the new module.
Which chip technology is used?
IGBT 4 Fast (Trench), according to the Semikron Danfoss product data.
What is the topology?
Half-Bridge (IGBT), according to the Semikron Danfoss product data.
Which housing does it use?
SEMITRANS 2, with dimensions of 94x34x30 mm, according to the Semikron Danfoss product data.
What is the current and voltage rating?
150 A at a voltage class of 1200 V, according to the Semikron Danfoss product data.
