Infineon introduces OptiMOS™ 7 application-optimized MOSFETs for industrial and consumer applications

Source: Infineon

Munich, Germany – 26 September 2025 – The rapid growth of power-hungry applications across various industries is placing unprecedented demands on power electronics in terms of power density, efficiency and reliability. Discrete power MOSFETs play a pivotal role in that context. An application-optimized approach opens new possibilities to further improve already highly advanced MOSFET technologies. Leveraging this use-case centric approach, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) is launching the OptiMOS™ 7 power MOSFET family for industrial and consumer markets, extending the already existing OptiMOS 7 automotive portfolio. Designed to provide the best fitting solution in their respective use case, the new OptiMOS 7 family offers products specifically for high performance switching, motor-drives, or R_DS(ON)-focused applications.

OptiMOS 7 25 V: Optimized for Switching Applications

The OptiMOS 7 25 V MOSFETs go beyond the one-size-fits-all approach, offering devices tailored to switching applications. The product variant targets applications such as intermediate bus converters (IBCs) with various topologies used in 48 V conversion for power AI cores, as well as switched-mode power supplies (SMPS) in telecommunications and traditional server applications. The portfolio includes two technology variants: devices optimized for hard-switching and soft-switching topologies. The hard-switching optimized devices feature an excellent Miller ratio, FOMs, and R_DS(ON)10, while the soft-switching optimized products deliver ultra-low R_DS(ON)45 and FOMQ_g. Compared to the OptiMOS™ 5 25 V, the new generation achieves up to 20 percent lower R_DS(ON) and up to 25 percent better FOMs, depending on the optimization type.

OptiMOS 7 40 V: Optimized for Motor Drives

The OptiMOS 7 40 V MOSFETs, designed for motor-drive applications, deliver lower R_DS(on), optimized gate characteristics, enhanced noise immunity, and a threefold wider safe operating area (SOA) compared to the previous generation. Their lower transconductance improves current distribution, reducing voltage overshoot, and boosts performance under harsh operating conditions. These devices are ideal for motor drives, power tools, and gardening applications, offering maximum reliability, efficiency, and power density.

Availability

The OptiMOS 7 25 V portfolio, optimized for switching, is available in source-down PQFN 3.3x3.3 packages with bottom and dual-side cooling variants in a center-gate footprint for flexible and optimal PCB design.
