Infineon Technologies, the largest player in the power semiconductor space, has introduced its latest generation of power MOSFETs. The company has started selling the first devices based on its OptiMOS 6 technology, designed for synchronous rectification in switched-mode power supply applications, including servers, personal computers and power chargers. The 40-V devices reduce on-state resistance by 30 percent compared to the previous generation.
The products, which were introduced at the annual Applied Power Electronics Conference, can be used to increase efficiency at high and low power outputs, without all the tradeoffs between high and low load conditions. Infineon's new OptiMOS technology also features higher switching performance, which can be maintained at a wide range of power outputs. That helps cut system costs in personal computers, chargers and other products, according to Infineon.
Infineon, which holds more than 25 percent of the $7 billion market for power MOSFETs, is seeing strong demand for its products, which are used in all sorts of electronic systems, ranging from computer chargers to electric cars. Last year, the company said it would spend $1.9 billion by 2024 to boost production of power semiconductors on 300-millimeter thin wafers. Infineon is trying to overcome an ongoing shortage of discrete power devices, including MOSFETs.
