QFET Planar MOSFETs

Fairchild Semiconductor’s new QFET® planar MOSFETs use advanced, proprietary technology to offer best-in-class operating performance for a wide range of applications, including power supplies, PFC (power factor correction), dc-dc converters, plasma display panels (PDP), lighting ballasts, and motion control.

These new C-Series (FQxxNxxC) and V2 Series (FQxxNxxV2) MOSFETs offer reduced on-state loss by lowering on-resistance (R_DS(on)) and reduced switching loss by lowering gate charge (Qg) and output capacitance (Coss); benefits that result from combining Fairchild’s proprietary DMOS and advanced planar stripe structure technologies. By using advanced QFET process technology, Fairchild can offer a 25% improved figure of merit (FOM) over competing planar MOSFET devices. For cost effectiveness, the new QFET series products are available in standard surface-mount and through-hole type packages (TO-92, TO-92L, TO-126).
