Fairchild Semiconductor Corp.'s Ultra FRFETTM Family

Fairchild Semiconductor Corp.'s Ultra FRFETTM Family

Fairchild's half-bridge solution - the Ultra FRFET family- optimizes designs by providing best-in-class reverse recovery time (trr) of 35ns - 65ns and the industry's smallest reverse recovery current (1.8 - 3.1A). These devices are part of a comprehensive portfolio of MOSFETs that offer designers a wide range of breakdown voltages (-500V to 1000V), state-of-the-art packaging and industry-leading FOM to deliver efficient power management anywhere electronic power conversion is needed. Fairchild's Ultra FRFET (Ultra Fast recovery MOSFET) is an industry first. Ultra FRFET works well with less than four diodes in high voltage backlight inverter and reduces costs in high voltage backlight inverters by approximately $0.20. Potential savings are expected to be over $26M in 2010 because the production of CCFL backlit LCD TV is 130M sets. The combination technology of lifetime control process and UniFETTM mosfets achieves soft reverse recovery characteristics and big diode dv/dt immunity guaranteeing 20V/ns compared with 4.5V/ns of normal MOSFET. The soft reverse recovery characteristics improved EMI characteristics in LCD TV sets and big diode dv/dt immunity improved system reliability during high frequency operation at high temperatures. When compared to alternate solutions offering a typical gate charge of only 16nC, the Ultra FRFET products are instrumental in reducing the turn-on and turn-off losses of the MOSFET through its significantly lower gate charge (Qg(typ) = 11nC). These products also feature a robust dv/dt immunity of 20V/ns, ensuring reliability and strong EMI performance to protect the LCD TVs from interference.
