SuperFET II and SuperFET II Easy-Drive MOSFETs

Fairchild recently added the SuperFET II MOSFET family using the latest Super Junction Technology to the high-voltage power MOSFET portfolio. With this technology, Fairchild provides best-in-class robust body diode performance in high-end, AC-DC SMPS applications such as servers, telecom, computing, industrial power supply, UPS/ESS, solar inverter, lighting applications as well as consumer electronics which require high power density, system efficiency and reliability.

Utilizing an advanced charge balance technology, Fairchild Semiconductor helps designers to achieve more efficient, cost-effective and high performance solutions that take up less board space and improve reliability by introducing the 600V N-channel SuperFET II MOSFET series.

Offered in two product families, the SuperFET II series is optimized for high-efficiency in high frequency switching applications, and SuperFET II Easy Drive series is optimized for ease of use and low EMI noise.
