Application-optimised MOSFETs for industrial and consumer applications

Infineon Technologies AG is launching the OptiMOS 7 power MOSFET family for industrial and consumer markets, extending the already existing OptiMOS 7 automotive portfolio. Designed to deliver the best-fitting solution in their respective use cases, the new family provides 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, delivering 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 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 to 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 40V MOSFETs, designed for motor-drive applications, deliver lower RDS(on), optimised gate characteristics, improved noise immunity, and a threefold wider 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 excellent for motor drives, power tools, and gardening applications, offering maximum reliability, efficiency, and power density.

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

The OptiMOS 7 40V motor-drives optimised portfolio includes SuperSO8 (5x6) and PQFN 3.3x3.3 packages.
