Genuine Semikron Danfoss SEMiX303GB17E4p: a 1700 V / 300 A IGBT module in SEMiX 3p 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 SEMiX303GB17E4p 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 SEMiX303GB17E4p; 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.
Before you replace it
- Gate driver compatibility and thermal paste / mounting torque
- Voltage class (1200 V or 1700 V) and current rating
- Housing (SEMITRANS 2/3, SEMiX) and terminal layout
Frequently asked questions
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.
What is the current and voltage rating?
300 A at a voltage class of 1700 V, according to the Semikron Danfoss product data.
Can you help me identify the right replacement?
Yes. Send us a photo of the label of the old part, or its full order code, and we will confirm the exact match or the official successor before quoting.
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.
