Vishay Intertechnology Inc. has rolled out 11 new devices to its 500 V series of high voltage MOSFETs designed to meet efficiency and high performance standards required in certain consumer, lighting and ATX/silver box PC SMPS applications.
The 11 MOSFETs feature the same low conduction and switching losses as the company’s E Series 600 V and 650 V devices and include 80-plus efficiency standards that are required for some of the target applications. The MOSFETs are built on Vishay’s second-generation Super Junction Technology and feature low on-resistance from 190 mΩ to 380 mΩ and ultra-low gate charge of 22 nC to 45 nC that allows it to be used in most power conversion applications, Vishay said.
Vishay said the low on-resistance helps to improve power density and to increase efficiency in typical hard-switched topologies such as power factor correction (PFC), two-switch forward converters and flyback converters. The devices are also designed to be rugged and withstand high energy pulse in the avalanche and commutation modes.
The 11 MOSFETs are available now in both sampling and production quantities with lead times of 16 to 17 weeks.
