Compatibility and replacement
Order with the complete Semikron type SKM50GB12T4; 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
- Chip generation (T4, E4, V, M7) when replacing in an existing drive
- Topology (half-bridge, chopper, sixpack)
- Gate driver compatibility and thermal paste / mounting torque
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.
What is the current and voltage rating?
50 A at a voltage class of 1200 V, according to the Semikron Danfoss product data.
Which chip technology is used?
IGBT 4 Fast (Trench), 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.
