MOSFETs suit high power density applications
The 600V n-channel SuperFET II mosfet series from Fairchild is said to be suitable for use in high end ac/dc switch mode power supplies in applications requiring high power density. The company says these in clude servers, telecom, computing and industrial power applications.

Available in two product families – the SuperFET II and SuperFET II Easy Drive – the mosfets offer a smaller stored energy in output capacitance for higher efficiency in light load conditions and a robust body diode for increased system reliability in resonant converters.
Using charge balance technology, the mosfets features a low on resistance and a lower gate charge performance to bring an overall reduction in the figure of merit.
