Compatibility and replacement
Order with the complete Semikron type SKB 52/16; 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.
The values in the table come from the official Semikron Danfoss product data; for full electrical ratings (VCE(sat), switching losses, thermal resistance) we send the datasheet with the quotation.
Before you replace it
- Surge current rating
- Housing and terminals (screw, fast-on, leads)
- Single- or three-phase bridge
Frequently asked questions
What is the topology?
Rectifier (Bridge), according to the Semikron Danfoss product data.
Which housing does it use?
SEMIPONT 3, with dimensions of 72x42x30 mm, according to the Semikron Danfoss product data.
What is the current and voltage rating?
50 A at a voltage class of 1600 V, according to the Semikron Danfoss product data.
What surge current can it handle?
425 A, 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.
