Semikron SEMiX303GB12E4p – IGBT Module 1200 V 300 A, Half-Bridge, SEMiX 3p. It is a genuine Semikron Danfoss IGBT module from the SEMiX range.
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 SEMiX303GB12E4p is a 1200 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 SEMiX303GB12E4p; 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.
Before you replace it
- Chip generation (T4, E4, V, M7) when replacing in an existing drive
- Topology (half-bridge, chopper, sixpack)
- Housing (SEMITRANS 2/3, SEMiX) and terminal layout
Frequently asked questions
What is the current and voltage rating?
300 A at a voltage class of 1200 V, according to the Semikron Danfoss product data.
What is the topology?
Half-Bridge (IGBT), 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 housing does it use?
SEMiX 3p, with dimensions of 150x62x17 mm, according to the Semikron Danfoss product data.
Which chip technology is used?
IGBT 4 (Trench), according to the Semikron Danfoss product data.
Can I get the datasheet?
The official manufacturer data is the source of the technical values above; we can send the datasheet with the quotation on request.
How fast can you deliver, and is there a warranty?
Air shipping usually takes 5 to 7 days once the part is ready, to almost any country. Each part is new and original with a 1-year warranty. Message us on WhatsApp with the order number for a quotation.
Before you order
