Compatibility and replacement
Order with the complete Semikron type SKKT 72/12 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
- SEMIPACK housing size
- Gate wiring and firing board
- Module type (SKKT thyristor/thyristor, SKKH thyristor/diode)
Frequently asked questions
What is the current and voltage rating?
70 A at a voltage class of 1200 V, according to the Semikron Danfoss product data.
What surge current can it handle?
1450 A, according to the Semikron Danfoss product data.
What is the topology?
Rectifier (Thyristor / Diode), according to the Semikron Danfoss product data.
Which housing does it use?
SEMIPACK 1, with dimensions of 93x20x30 mm, 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.
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.
Can I get a price and delivery time?
