Genuine Semikron Danfoss SEMiX453GB17E4p: a 1700 V / 450 A IGBT module in SEMiX 3p 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 SEMiX453GB17E4p; 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 (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?
SEMiX 3p, with dimensions of 150x62x17 mm, according to the Semikron Danfoss product data.
What is the current and voltage rating?
450 A at a voltage class of 1700 V, according to the Semikron Danfoss product data.
