Infineon’s Power Semiconductor Blitz: Two Product Launches and an Analyst Upgrade Converge
Veröffentlicht: 03.06.2026 um 04:53 Uhr, Redaktion boerse-global.de
Infineon has been on a tear this year, its shares more than doubling since January as investors bet that the chipmaker’s strength in power management will make it a key beneficiary of the artificial-intelligence infrastructure buildout. On Tuesday, that thesis received a double dose of confirmation: a fresh product rollout targeting the surging energy demands of AI data centers, and a Wall Street analyst who raised his price target by nearly 30%.
The stock closed at €87.85, a new 52-week high, leaving it roughly 58% above its 50-day moving average. From its September 2025 trough of €31.38, the shares have almost tripled.
A 24-kW Battery Backup Unit with 99% Efficiency
Infineun unveiled what it calls the world’s first 24-kilowatt battery-backup-unit reference design that connects directly from a battery stack to an 800-volt DC bus, bypassing conventional intermediate stages. The design marries 650-V and 1200-V silicon carbide (SiC) technology to achieve a power density of 450 watts per cubic inch and an efficiency exceeding 99% — all within the same physical footprint as existing low-voltage solutions.
The timing is deliberate. Data centers globally are migrating to high-voltage DC distribution to cope with the exploding energy consumption of AI workloads. Infineon is positioning itself not just as a component supplier but as a system-level enabler, a strategy it flagged in May when it joined the NVIDIA MGX AI Factory Ecosystem and agreed to supply power-management chips for 800-VDC architectures.
Should investors sell immediately? Or is it worth buying Infineon?
Normally-Off JFETs Enter Volume Production
Alongside the battery backup announcement, Infineon confirmed that its first 750-V and 1200-V CoolSiC JFETs in the Q-DPAK package have entered series production. The company quotes RDS(on) values of 1.6 milliohms at 750 V and 2.3 milliohms at 1200 V, which it describes as among the lowest available in those voltage classes. A 1200-V JFET in the TO-247-4 package, with an on-resistance starting at 5.0 milliohms, is designed as a drop-in replacement for existing SiC MOSFET designs without board modifications.
The new “Normally-Off” series pairs a CoolSiC JFET with an OptiMOS low-voltage MOSFET in a single package. Infineon offers two configurations: a Dual-Drive variant that provides separate gate access to both transistors, and a Cascode variant that exposes only the MOSFET gate, allowing engineers to use standard gate drivers. The goal is to simplify upgrades for existing designs, removing the need for new driver infrastructure.
In AI data centers, these devices handle tasks such as fault isolation, battery disconnect switches, and hot-swap circuits. Semiconductor-based protection switches faster than electromechanical systems, a critical advantage when downtime directly reduces compute capacity.
Jefferies Sees a Structural Upcycle
Analyst Janardan Menon of Jefferies raised his price target on Infineon from €75 to €96, maintaining a “Buy” rating. He argues that the company will benefit in the 2026/2027 and 2027/2028 financial years from rising demand, higher capacity utilization, and firmer pricing in power-management chips for AI applications. His earnings estimates for those two periods sit roughly 11% above the consensus, signaling that he expects the strength of the current cycle to be priced in earlier than his peers anticipate.
Menon also sees the automotive and industrial recovery as an additional tailwind, complementing the AI narrative rather than competing with it.
Infineon at a turning point? This analysis reveals what investors need to know now.
The broader picture is reinforced by recent moves from rivals: STMicroelectronics simultaneously raised its revenue targets for the data-center segment, an indication that demand for power semiconductors in AI infrastructure is not a fleeting boom but a structural transformation of global power distribution architecture.
Confirming the Outlook
Infineon had already raised its guidance for fiscal 2026 on May 6, projecting a significant year-on-year revenue increase and a segment-result margin of around 20%. Adjusted free cash flow is expected to reach approximately €1.65 billion.
Both new product lines — the 24-kW battery backup unit and the CoolSiC JFETs — will be showcased at PCIM Europe from June 9 to 11 in Nuremberg, where Infineon will also highlight solid-state transformers, robotics, and charging solutions. The event promises to provide further grist for investors already digesting a year that has seen the stock more than double and a technology roadmap that now extends from the battery stack to the 800-V bus, all built on SiC.
