Genuine Semikron Danfoss SKM145GB176D: a 1700 V / 100 A IGBT module in 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.

The SKM145GB176D is a 1700 V IGBT module and comes as bare module without pre-applied thermal interface material or lid, ideal for custom assembly processes.

Compatibility and replacement
Order with the complete Semikron type SKM145GB176D; 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
- Housing (SEMITRANS 2/3, SEMiX) and terminal layout
- Chip generation (T4, E4, V, M7) when replacing in an existing drive
- Voltage class (1200 V or 1700 V) and current rating
Frequently asked questions
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.
Which chip technology is used?
IGBT 3 (Trench), according to the Semikron Danfoss product data.
What is the current and voltage rating?
100 A at a voltage class of 1700 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.
Can I get the datasheet?
