Infineon has put a concrete product behind its AI infrastructure ambitions, launching a family of 750- and 1200-volt CoolSiC JFETs that bring normally-off operation to power distribution in hyperscale data centres. The silicon-carbide devices, now in volume production, target fault isolation, battery disconnect switches and hot-swap designs — areas where semiconductor-based protection can cut switching times below what electromechanical relays manage.
The move strengthens a narrative that has already propelled the stock to a fresh 52-week high. Infineon closed at 88.05 euros on Tuesday, having added 54.85% over the past 30 days and 129.87% year to date. The product announcement and the rally are feeding off each other: the chips give analysts hard evidence of execution, while the elevated share price lifts the company’s profile among investors chasing exposure to the AI power chain.
Jefferies underscored that theme on Tuesday, raising its price target from 75 to 96 euros and keeping a “Buy” rating. Analyst Janardan Menon pointed to power-management solutions for AI as the key catalyst, projecting rising demand, higher capacity and improving prices in the 2026/2027 financial year. He also cited a brighter outlook in the automotive and industrial segments, where Infineon had flagged “extremely strong demand” for data-centre power supplies back in early May.
Should investors sell immediately? Or is it worth buying Infineon?
The quarterly numbers published earlier this month back the case. Revenue hit 3.812 billion euros in the latest period, up from 3.662 billion in the prior quarter, while operating profit climbed to 458 million euros from 388 million. Earnings per share from continuing operations came in at 0.23 euros. The Power & Sensor Systems segment, which directly serves server and AI data-centre customers, saw revenue rise to 1.260 billion euros and segment margin widen to 20.4%. Green Industrial Power also recovered, with revenue moving to 403 million euros from 349 million, lifted by demand from energy infrastructure, HVAC and household appliances.
The new JFETs add a tactical edge. Infineon’s normally-off portfolio combines a CoolSiC JFET with an OptiMOS low-voltage MOSFET inside a single package. Designers can choose between a dual-drive version that gives separate gate access to both transistors or a cascode version that exposes only the MOSFET gate and works with standard gate drivers — a straightforward upgrade path for existing systems. The company claims the RDS(on) values — 1.6 milliohms at 750 volts and 2.3 milliohms at 1,200 volts — rank among the lowest available in those voltage classes.
Looking ahead, Infineon expects third-quarter revenue of about 4.1 billion euros, based on a euro-dollar exchange rate of 1.17. For the full 2026 financial year, it now forecasts a “significant” revenue increase, a segment-result margin around 20% and adjusted free cash flow of roughly 1.65 billion euros. The AI data-centre power business alone is projected to generate about 1.5 billion euros this year and 2.5 billion euros next year. The new CoolSiC products will be on display at PCIM Europe in Nuremberg from 9 to 11 June, alongside solid-state transformers, robotics and charging solutions — a line-up that frames Infineon’s growth story as more than just a cyclical auto recovery.
