Infineon Technologies AG recently introduced 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 R DS(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 R DS(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 R DS(on) and more than 30 percent improvement in FOMs (R DS(on) x Q g and Q gd), 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 R DS(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 .

OptiMOS 6 100 V is now available in SuperSO8 5x6 and PQFN 3.3x3.3 packages in a broad range of R DS(on) classes from industry best-in-class to price/performance optimized. More information is available at
