Infineon Technologies (DE0006231004) emphasizes its strategic push in power semiconductors for energy-efficient systems. The company recently highlighted its ongoing collaboration with Siemens on smart infrastructure and sustainable power solutions, with its stock trading on Xetra alongside peers like STMicroelectronics and NXP.

Siemens collaboration in power electronics

Infineon Technologies AG and Siemens AG have been teaming up in power electronics to support smart buildings and energy infrastructure, including joint work on efficient drives and industrial systems as outlined in Infineon presentations and Siemens partner communications. The partnership aims to use Infineon power semiconductors in Siemens applications ranging from industrial automation to energy management, targeting reduced energy losses and higher system efficiency.

According to Infineon, power devices such as IGBTs and MOSFETs are central to its offering for Siemens drives and converters, enabling higher switching frequencies and compact designs in industrial and grid applications. A focus area is decarbonization of energy systems, where Infineon chips help increase the efficiency of inverters, converters, and power supplies used in Siemens solutions for renewable integration and building technologies.

Position in the global chip sector

Infineon is positioned as a leading supplier of power semiconductors globally, competing with companies such as STMicroelectronics, NXP, and ON Semiconductor in automotive and industrial markets. The group generates a significant share of its revenue from automotive electronics, where it supplies power chips for electric vehicles, on-board chargers, and inverters, as detailed in its investor materials.

In Europe, Infineon trades on Xetra and is part of major indices like the DAX, giving it high visibility among institutional investors focused on the semiconductor value chain. Analysts regularly compare its valuation and margins with international peers, tracking factors such as capacity expansion, pricing discipline, and exposure to cyclical end markets like automotive and industrial automation.

How Infineon makes its money

Infineon Technologies generates most of its revenue from semiconductor solutions in four segments: Automotive, Green Industrial Power, Power & Sensor Systems, and Connected Secure Systems, according to its annual and quarterly reports. Products include power chips, microcontrollers, and sensors, which are sold to car makers, industrial equipment manufacturers, and electronics companies worldwide.

Where the stock trades today

Infineon Technologies stock trades on Xetra in euros, with current prices and market capitalization published by Deutsche Boerse and financial portals that track DAX semiconductor constituents.
