Compatibility and replacement
Order with the complete Semikron type SKM300GB17E4; 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
- Topology (half-bridge, chopper, sixpack)
- Housing (SEMITRANS 2/3, SEMiX) and terminal layout
- Voltage class (1200 V or 1700 V) and current rating
Frequently asked questions
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?
SEMITRANS 3, with dimensions of 106x62x31 mm, 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.
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 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.
Before you order
Compare the complete order number on the old unit with this page, including the suffix: in most ranges the last characters set the coil voltage, current range or version. If the label is worn, send us a photo and we will identify the part.
