As of 5 Oct 2026, 17:35What does Infineon do?
Infineon, based near Munich, is Germany’s largest chipmaker. It doesn’t make computer processors. Instead it focuses on power semiconductors: chips that switch and control electricity efficiently. You find them in cars, charging stations, solar systems and, more and more, in the power supply of AI data centers. Infineon was spun off from Siemens in 1999.
Almost every new car contains Infineon chips, for things like airbags, power windows and engine control. Many bank cards also use Infineon security chips.
