Semikron

Semikron is a global semiconductor manufacturer headquartered in Germany. The company designs and manufactures power semiconductor devices, including insulated-gate bipolar transistor (IGBT) modules, diodes, and thyristors. Its products are used in applications that require efficient conversion and control of electrical power. Key markets served include automotive propulsion systems, renewable energy inverters, industrial motor drives, and traction equipment. Semikron supplies both original equipment manufacturers and aftermarket customers worldwide.

The organization maintains a presence in multiple countries, with offices and production sites located across Europe, Asia, and the Americas. This international footprint enables it to support customers close to their manufacturing and service locations. The ransomware incident described in August 2022 affected IT systems across these international offices and production sites. In response to the attack, Semikron engaged external cybersecurity and forensic experts to investigate the breach. The company also collaborated with law enforcement authorities and prepared to notify affected partners if data exfiltration was confirmed.

Semikron’s core competency lies in the development of high-power semiconductor solutions that efficiently handle high voltages and currents. The company emphasizes reliability and performance, which are critical for demanding sectors such as electric vehicles and grid-connected renewable energy systems. Its engineering focus includes thermal management and packaging technologies that improve module longevity under harsh operating conditions. The ransomware event prompted Semikron to reinforce its IT security posture, reflecting a broader commitment to protecting both operational technology and intellectual property. Semikron positions itself as a specialist supplier of power electronics components that contribute to the efficiency and sustainability of modern electrical systems.
