OptiMOS™ 6 100 V Significantly Improves Technology To Set A New Industry Standard For High Switching Frequency Applications


For modern switch-mode power supplies  (SMPS) and battery-powered applications, there is a clear trend towards higher  efficiency and improved reliability. Supporting this trend, Infineon Technologies AG  (FSE: IFX / OTCQX: IFNNY) introduces the OptiMOS™ 6 100 V with a new power  MOSFET technology. The new technology is specifically optimized for high switching  frequency applications such as telecom and solar, where losses are associated with  charges (switching) and on-state resistance (conduction). At the same time, due to  the best-in-class RDS(on) and wider safe operating area (SOA), it is also ideal for  battery-powered applications (BPA) and battery management systems (BMS). 


Taking advantage of a novel design concept, the OptiMOS 6 100 V family of  MOSFETs comes with improved RDS(on) and industry’s best figures-of-merit (FOMs).  It combines the benefits of exceptionally low on-state resistance and superior  switching performances. The unique features of OptiMOS 6 allow for easier thermal  design and less paralleling, leading to excellent efficiency, improved power density,  system cost reduction, and prolonged lifetime.

Especially in the telecom market, OptiMOS 6 is a “game-changer” by achieving 18  percent lower RDS(on) and more than 30 percent improvement in FOMs (RDS(on) x Qg and Qgd), compared to the state-of-the-art OptiMOS 5. In a 600 W, -(36-60) V to 12 V  ZVS buck-boost converter, the OptiMOS 6 in SuperSO8 package with 2.2 mΩ can  achieve one percent higher efficiency than OptiMOS 5 BSC027N10NS5 (2.7 mΩ)  across the whole load range. This results in a 7 W lower power loss due to improved  charges and RDS(on), enabling up to 15 percent higher power density. Among the key  benefits, the new technology in the 100 V range allows for lower conduction and  switching losses and minimizes the necessity for paralleling parts. 


OptiMOS 6 100 V is an energy efficient solution that contributes to a greener world.  In the framework of telecom power system, by switching to the new MOSFET  technology, the annual electricity saving potential equals the electricity consumption of 170 households. The devices help to reduce the energy consumption by one  million Euros over a time span of ten years.
