Infineon Technologies OptiMOS™ 6 Power MOSFETs

Infineon Technologies OptiMOS™ 6 Power MOSFETs offer next generation, cutting-edge innovation, and best-in-class performance. The OptiMOS 6 family utilizes thin wafer technology that enables significant performance benefits. Compared to alternative products, the OptiMOS 6 Power MOSFETs have a reduced RDS(ON) of 30% and are optimized for synchronous rectification.

Additionally, the devices have improved figure of merits (FOM - RDS(on) x Qg and Qgd) allowing designers to increase efficiency and reduce system cost. The OptiMOS 6 maintains the advantage outputting a higher power, where the RDS(on) losses are getting more dominant, leading to better performance throughout the whole operating range.


Infineon Technologies OptiMOS™ 6 40V Power MOSFETs are optimized for a variety of applications and circuits, including synchronous rectification in switched mode power supplies (SMPS) in servers, desktop PCs, wireless chargers, quick chargers, and ORing circuits. In SMPS applications, OptiMOS 6 is the perfect solution for optimizing efficiency over a wide range of output power, avoiding the trade-off between low and high load conditions.

The OptiMOS 6 40V Power MOSFETs are available in two different packages, the SuperSO8 - 5mm x 6mm with RDS(on) ranging from 5.9mΩ down to 0.7mΩ, and the PQFN 3.3mm x 3.3mm with RDS(on) ranging from 6.3mΩ down to 1.8mΩ.
