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-optimised approach opens new possibilities to further improve already highly advanced MOSFET technologies. Harnessing this use-case centric approach, Infineon Technologies is launching the OptiMOS 7 power MOSFET family for industrial and consumer markets, extending the already existing OptiMOS 7 automotive portfolio. Engineered 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 RDS(ON)-focused applications.
The OptiMOS 7 25V 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 48V 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 optimised for hard-switching and soft-switching topologies. The hard-switching optimised devices feature an excellent Miller ratio, FOMs, and RDS(ON)10, while the soft-switching optimised products deliver ultra-low RDS(ON)45 and FOMQg. Compared with the OptiMOS 5 25V, the new generation achieves up to 20% lower RDS(ON) and up to 25% better FOMs, depending on the optimisation type.
The OptiMOS 7 40 V MOSFETs, designed for motor-drive applications, deliver lower RDS(on), optimised 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 well suited for motor drives, power tools, and gardening applications, offering maximum reliability, efficiency, and power density.
