Compatibility and replacement
Order with the complete Semikron type SKB 25/16; 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.
Replacement checklist
- Mounting and heatsink
- Housing and terminals (screw, fast-on, leads)
- Voltage class and current rating
Frequently asked questions
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.
What surge current can it handle?
320 A, according to the Semikron Danfoss product data.
What is the topology?
Rectifier (Miniature Bridge), according to the Semikron Danfoss product data.
Which housing does it use?
G 10b, with dimensions of 29x29x10 mm, according to the Semikron Danfoss product data.
What is the current and voltage rating?
17 A at a voltage class of 1600 V, according to the Semikron Danfoss product data.
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.
