Automotive DirectFET® Power MOSFETs Deliver Impressive Power Density

Fri, 01/22/2010 - 10:01am
International Rectifier introduces the AUIRF7739L2 and AUIRF7665S2 automotive DirectFET®2 power MOSFETs that deliver impressive power density, dual-sided cooling and low parasitic inductance and resistance in a robust, reliable and AEC-Q101 qualified package for automotive applications. These first automotive DirectFET2 devices from IR are entirely lead-free and offer overall system level size and cost reductions along with good performance and efficiency when compared to traditional standard plastic packaged components. The AUIRF7739L2 in the new large can package delivers the industry’s lowest RDS(on) of 0.7mOhm (typical) at 40V in a given PCB area. Moreover, the large can features a 60 percent smaller footprint and 85 percent lower profile than a D2PAK. The AUIRF7665S2 small can device is optimized for very low gate charge and exhibits extremely low parasitics for fast and efficient switching performance. The DirectFET2 MOSFET is ideal for automotive switching applications including the output stage of Class D Audio amplifiers as well as DC-DC converters and fuel injection systems.
