Semikron is a German-based independent manufacturer of power semiconductor components. The company was founded in 1951 by Dr. Friedrich Josef Martin in Nuremberg. In 2019, the company had a staff of more than 3,000 people in 24 subsidiaries (world-wide) with production sites in Germany, Brazil, China, France, India, Italy, Slovakia, and the USA.
In the field of diode/thyristor modules, Semikron is the market leader with a 30% share of the worldwide market.[3]
Products
Semikron's product range consists of 11,600 different power semiconductors from 1 kW to 10 MW, including chips, discrete diodes/thyristors, power modules (IGBT/MOSFET/diode / thyristor/CIB/IPM), driver and protection components and integrated subsystems.
Amongst other developments, Semikron invented the world's first isolated power module.
