Fairchild’s High-Voltage MOSFETs Provide Robust Body Diode Performance in AC-DC Applications

High-end, AC-DC switch-mode power supply (SMPS) applications such as servers, telecom, computing, and industrial power applications require high power density, and to be successful, designers need cost-effective solutions that take up less board space and improve reliability. Fairchild Semiconductor helps designers with these challenges by introducing the 600V N-channel SuperFET® II MOSFET series. Offered in two product families, the SuperFET II and SuperFET II Easy Drive, these MOSFETS offer a smaller stored energy in output capacitance (Eoss) for higher efficiency in light-load conditions and best-in-class robust body diode for increased system reliability in resonant converters.

Utilizing an advanced charge balance technology, these MOSFETs provide a significantly low on-resistance and a lower gate charge (Qg) performance for a lower figure of merit (FOM). The devices are comprised of several integrated features to assist in a simplified design that reduces component count for a more efficient, cost-effective design including a gate resistor (Rg) that greatly reduces gate oscillation and improves overall system performance.
