What Infineon Technologies makes

Infineon Technologies AG is a semiconductor company, not a contract manufacturer in the Tier-1 fabrication sense, but it functions as a critical Tier-1 supplier to virtually every major automaker: the chips it designs and produces go directly into vehicle powertrains, body electronics, safety systems, and cockpit modules, making it a direct and substantial line item in automotive bills of materials.

The automotive segment, which the company calls ATV, accounts for roughly half of total revenue and is organized around four product families. Power semiconductors cover power MOSFETs under the OptiMOS brand, IGBT modules packaged in the HybridPACK series, and silicon carbide power modules used in EV traction inverters and onboard chargers. Microcontrollers are sold under the AURIX brand, designed to the ISO 26262 functional safety standard for powertrain, chassis, and ADAS applications; per the company's own April 2026 market position release, Infineon holds 36 percent market share in automotive microcontrollers. The sensor portfolio, branded XENSIV, includes radar chips for driver-assistance systems, tire pressure monitoring ICs, and current sensors. Security chips and embedded secure elements round out the automotive lineup, covering vehicle access, V2X communications, and over-the-air update authentication.

Beyond automotive, Infineon supplies the industrial power, consumer, and data-center markets through its Green Industrial Power (GIP), Power and Sensor Systems (PSS), and Connected Secure Systems (CSS) segments. GIP covers power semiconductors for motor drives, renewable energy converters, and grid infrastructure. PSS addresses consumer electronics power management, Wi-Fi and Bluetooth connectivity chips (the Cypress portfolio, acquired in 2020), and MEMS microphones under the XENSIV brand. CSS covers security controllers and hardware security modules. As of the fourth quarter of FY2026, the company is implementing a revised segment structure.

In September 2026, Infineon announced an agreement to sell its NOR Flash and F-RAM memory business to Winbond Electronics (Taiwan) for $1.12 billion cash, sharpening its focus on power semiconductors, microcontrollers, sensors, and security. The transaction is expected to close in the second half of 2027 pending regulatory approval. Infineon retains its specialty memory lines including SRAM, HYPERRAM, nvSRAM, and radiation-hardened memory products.

Financial performance

Per the Berylls by AlixPartners Top-100 Automotive Suppliers study for FY2025, Infineon's automotive-sector revenue was approximately €7.3 billion, down 11.5 percent from €8.3 billion in FY2024. The company reported a 21.5 percent operating income margin on that automotive base, a compression from 23.8 percent in the prior year but still among the highest margins in the supplier ranking. The Berylls figure covers automotive-only revenue; Infineon's total company revenue across all end markets is substantially larger.

At the full-company level, the trajectory turned sharply positive entering FY2026. The Q3 FY2026 press release published August 5, 2026, reported record quarterly revenue of €4.172 billion and a segment result margin of 19.1 percent, with demand from AI data center customers described as the principal growth driver. The company raised its FY2026 total revenue guidance to approximately €16.3 billion and forecast a segment result margin of around 20 percent for the full year. Management separately noted that multi-year capacity reservation agreements with leading AI customers represent a cumulative high single-digit billion euro revenue volume. Automotive order intake, per the CEO's Q3 commentary, is picking up noticeably.

Infineon employs roughly 55,000 to 58,000 people globally, per available estimates, with manufacturing, R&D, and sales operations across Europe, Asia, and the Americas. The fiscal year runs October 1 to September 30.

Ownership and history

Infineon Technologies AG was created on April 1, 1999, when Siemens AG spun off its semiconductor operations as a separate company. The underlying semiconductor activities trace to Siemens' component division from the 1950s. Infineon went public on the Frankfurt Stock Exchange on May 13, 2000 (ticker: IFX) and trades on the OTCQX market in the United States under the symbol IFNNY.

Headquarters are at Am Campeon 1-15, 85579 Neubiberg, Germany, near Munich. The campus is the company's primary executive and R&D base. Infineon has no parent organization; it is an independent publicly traded company, subject to the standard governance of a German Aktiengesellschaft. The management board as of 2026 consists of Jochen Hanebeck (CEO, appointed April 1, 2022, contract through March 2027), Dr. Sven Schneider (CFO), Elke Reichart, Andreas Urschitz, and Alexander Gorski. Dr. Herbert Diess chairs the supervisory board.

The company has grown substantially through acquisition: Cypress Semiconductor (2020, $9.4 billion) brought Wi-Fi, Bluetooth, and Flash memory capabilities along with engineering resources in the United States. The pending NOR Flash sale to Winbond partially reverses the memory portion of that acquisition as Infineon prioritizes higher-margin analog and mixed-signal work.

Manufacturing is distributed across multiple continents. The September 2026 opening of a next-generation backend manufacturing facility in Bangkok represents a continued investment in Asian assembly and test capacity, described by the company as its next-generation backend hub.

Certifications and quality

Per the company's certifications page, Infineon holds ISO 9001 and IATF 16949 certification worldwide, covering design and manufacturing of semiconductor components. The company also holds AS 9100 certification for aerospace-grade quality, and its products are evaluated against ISO 26262 functional safety requirements for automotive applications. A TUV NORD certificate for the Warstein, Germany facility (IATF 16949:2016) was publicly available as of the time of research. The company operates a stated zero-defect quality philosophy across its automotive product lines, and its automotive microcontrollers and power devices are designed, tested, and qualified to AEC-Q standards.

Known customers

BMW Group and Infineon announced a strategic collaboration agreement in February 2026 focused on semiconductors for software-defined vehicles, covering power modules, microcontrollers, and sensors. HL Klemove (a Hyundai-Mobis subsidiary focused on advanced driver-assistance systems) signed a memorandum of understanding with Infineon in January 2026 covering automotive innovation for software-defined vehicles. Beyond these publicly documented partnerships, Infineon describes strong customer positions across European, Chinese, South Korean, North American, and Japanese automakers, consistent with its stated position as global number one in automotive semiconductors for six consecutive years per its April 2026 press release. Specific OEM program details beyond those named above are not individually documented by the company in publicly available materials reviewed for this profile.
