Attain High Efficiency In Hard Switching Applications


The launch of all new voltage MOSFET cuts energy loses by 50 per cent in hard switching applications intended to deliver increased power density and reduce cost with the highest level of reliability, making it an ideal solution for energy efficient applications such as telecom systems, uninterruptible power supplies (UPS), motor control, industrial power supplies and DC/AC inverters.

According to Infineon release, “The new OptiMOS 300 V incorporates fast diode technology that allows to deliver 70 per cent lower reverse recovery charge Qrr resulting in a smooth body diode behaviour and minimises voltage overshoot by providing headroom for voltage spikes. Additionally, 110V AC UPS can now be realised with OptiMOS 300V.” The release also mentions that OptiMOS 300 V offered in TO-220 package provides the industry’s best RDS (on) with more than 58 per cent lower Figure of Merit (FoM).

Further in an interview Richard Kuncic, Vice President & General Manager Business Line DC/DC at Infineon Technologies AG said, “With 300 V blocking capability, Infineon extends the benchmark OptiMOS technology into a so far non-mainstream voltage class to support evolving applications such as multilevel converters. Due to superior performance of OptiMOS technology and the wide application spectrum, we expect this voltage class to become a new standard in the power MOSFET market.”
