Semikron SKKH 72/16 E – Thyristor/Diode Module 1600 V 70 A, SEMIPACK 1. It is a genuine Semikron Danfoss thyristor module from the SEMIPACK range.
Thyristor modules switch on with a gate pulse and stay on until the current falls to zero, which makes them the standard part for phase-angle control of AC and DC power.

Compatibility and replacement
Order with the complete Semikron type SKKH 72/16 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.
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.
What to check first
- Module type (SKKT thyristor/thyristor, SKKH thyristor/diode)
- SEMIPACK housing size
- Repetitive voltage class (/12 = 1200 V, /16 = 1600 V)
Frequently asked questions
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.
What is the current and voltage rating?
70 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.
Before you order
