Compatibility and replacement
Order with the complete Semikron type SKKT 330/12 E; 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
- Average current rating and surge current
- SEMIPACK housing size
- Module type (SKKT thyristor/thyristor, SKKH thyristor/diode)
Frequently asked questions
What is the current and voltage rating?
309 A at a voltage class of 1200 V, according to the Semikron Danfoss product data.
Is the baseplate isolated?
Yes. The module is built with an isolated baseplate, so it can be mounted directly on a heatsink that carries other components; always use thermal paste and the specified mounting torque.
Which housing does it use?
SEMIPACK 3, with dimensions of 115x50x52 mm, according to the Semikron Danfoss product data.
What is the topology?
Rectifier (Thyristor / Diode), according to the Semikron Danfoss product data.
What surge current can it handle?
8000 A, according to the Semikron Danfoss product data.
