Infineon Rolls Out OptiMOS-7 for AI Servers as Jefferies Reaffirms EUR 96 Target

Infineon has pushed its OptiMOS-7 family into the market, launching a 40-volt MOSFET portfolio aimed at power conversion in AI servers, data centres and telecoms infrastructure. The company said the products are available now and already running in volume production.

The rollout lands alongside a broader power-supply push. On 21 October, Infineon unveiled a collaboration with NVIDIA covering GaN-based power conversion systems for 800-VDC AI data centres — a tie-up that now sits next to the new MOSFET line in the company's AI infrastructure story.

Analysts Train Sights on Hyperscaler Spending

Jefferies confirmed its buy rating on Infineon yesterday with a price target of EUR 96, according to media reports, with analyst Janardan Menon pointing to capital spending by major cloud and data centre operators. The stock responded to the product news by climbing 1.9% to EUR 51.91.

That gain extends a recovery from the previous session, when shares edged up 0.2% to close at EUR 50.95. The earlier advance had been a rebound after Intel's weak fourth-quarter 2026 outlook weighed on European semiconductor names on Friday, with Infineon among the weakest DAX constituents — a move media reports attributed to Intel rather than to any fresh analyst action on Infineon itself.

Qualcomm Agreement Adds Automotive Angle

Supporting the stock in that stretch was a technology agreement with Qualcomm Technologies. The two companies will jointly develop a microcontroller-based subsystem for Snapdragon Ride reference platforms in software-defined vehicles. Infineon's design is intended to complement the vehicle computer platform, with the company naming high-performance computing and in-vehicle artificial intelligence as target applications.

Villach Expansion Anchored by State Aid

Behind the product momentum sits a substantial manufacturing bet. Roughly a week ago, Infineon announced around EUR 1.1 billion of investment in existing cleanrooms at its Villach site, with the funds to be deployed through 2034. The plan calls for high-volume production of GaN power semiconductors on 300-millimetre wafers, with manufacturing slated to begin by the end of 2027.

The European Commission cleared EUR 319 million in Austrian state aid for Infineon Technologies Austria on Thursday, backing modernisation of the Villach semiconductor facility and the "Empowering Fab" project for high-volume GaN power semiconductor production. The approval falls under the European Chips Act.

Site Network Widens Beyond Austria

Infineon's footprint expanded elsewhere too. On 28 October it opened a new office, development and laboratory building in Warstein, where around 350 employees are expected to move in, with roughly 1,200 square metres of laboratory space planned.

On 22 October, the chipmaker teamed up with UnternehmerTUM Accelerator, Microsoft and NVIDIA to launch the Physical AI Growth Lab. The equity-free accelerator programme targets start-ups in physical AI, robotics and industrial AI and is set to run from January to April 2027.

Investors will get their next hard numbers on 10 November, when Infineon reports results for the fourth quarter and the 2026 fiscal year.
