The Semikron SKM400GB176D is a IGBT module rated 300 A at 1700 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 SKM400GB176D; 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.
If the marking of the old module is burnt or unreadable, send us a photo and the drive model and we will confirm the correct Semikron type before quoting.
What to check first
- Gate driver compatibility and thermal paste / mounting torque
- Housing (SEMITRANS 2/3, SEMiX) and terminal layout
- Chip generation (T4, E4, V, M7) when replacing in an existing drive
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.
What is the topology?
Half-Bridge (IGBT), according to the Semikron Danfoss product data.
What is the current and voltage rating?
300 A at a voltage class of 1700 V, according to the Semikron Danfoss product data.
Which chip technology is used?
IGBT 3 (Trench), according to the Semikron Danfoss product data.
Which housing does it use?
SEMITRANS 3, with dimensions of 106x62x31 mm, according to the Semikron Danfoss product data.
