Infineon Releases OptiMOS 3 75V MOSFET Family

Infineon Technologies has announced production availability of its OptiMOS 3 75V power MOSFET family. The new devices feature improved on-state resistance [RDS(on)] and Figure of Merit (FOM) characteristics that enable reduced power losses and improved overall efficiency under all load conditions for switched-mode power supplies (SMPS), as well as power applications like motor control and fast switching Class D amplifiers.

The OptiMOS 3 75V power MOSFET family is ideal for synchronous rectification in AC/DC SMPSes, such as those used in desktop computers and computer servers manufactured for global markets. New energy efficiency targets, such as the 80PLUS Gold requirement promoted by Climate Savers Computing Initiative, call for approximately a 10 percent improvement in the energy efficiency of computers compared to the current requirements of the U.S. Energy Star program. With OptiMOS 3, Infineon helps to meet these specifications. The OptiMOS 3 device in a space-saving SuperSO8 package features 40 percent lower RDS(on) and 34 percent lower FOM than alternative devices, which translates to a re-duction of power losses up to 10 percent in the synchronous rectification stage of the SMPS.
