The Semikron SKM300GB12E4 is a IGBT module rated 300 A at 1200 V, supplied in the SEMITRANS 3 housing.
In a frequency inverter the IGBT module converts the DC bus back into a variable AC output; its voltage class, current rating and housing decide which drives and gate drivers it fits.

Compatibility and replacement
Order with the complete Semikron type SKM300GB12E4; 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
- Housing (SEMITRANS 2/3, SEMiX) and terminal layout
- Topology (half-bridge, chopper, sixpack)
- Chip generation (T4, E4, V, M7) when replacing in an existing drive
Frequently asked questions
Which housing does it use?
SEMITRANS 3, with dimensions of 106x62x31 mm, according to the Semikron Danfoss product data.
What is the current and voltage rating?
300 A at a voltage class of 1200 V, according to the Semikron Danfoss product data.
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 (Trench), according to the Semikron Danfoss product data.
What is the topology?
Half-Bridge (IGBT), according to the Semikron Danfoss product data.
Do you supply larger quantities for projects?
Yes. For panel builders, OEMs and plant projects we quote complete lists; send the bill of materials on WhatsApp or through the inquiry form.
