Semikron SKD 25/16 – Bridge Rectifier 1600 V 20 A, G 11b. It is a genuine Semikron Danfoss bridge rectifier from the Fast-on range.
Bridge rectifiers convert single- or three-phase AC into DC; in drives and power supplies they form the input stage that feeds the DC-link capacitors.

Compatibility and replacement
Order with the complete Semikron type SKD 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.

Frequently asked questions
What surge current can it handle?
320 A, according to the Semikron Danfoss product data.
Which housing does it use?
G 11b, with dimensions of 29x29x10 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.
What is the topology?
Rectifier (Miniature Bridge), according to the Semikron Danfoss product data.
What is the current and voltage rating?
20 A at a voltage class of 1600 V, according to the Semikron Danfoss product data.
Do you supply larger quantities for projects?
Yes. For panel builders, OEMs and plant projects we quote complete lists; send the bill of materials on WhatsApp or through the inquiry form.
