Power MOSFETs have lowest RDS(on), target automotive apps
The AUIRF7739L2 and AUIRF7665S2 DirectFET2 power MOSFETs are presented as providing the automotive industry’s lowest RDS(on) . They also feature dual-sided cooling, and low parasitic inductance and resistance in an AEC-Q101-qualified package for automotive applications. These devices are lead-free and offer overall system-level size and cost reductions along with superior performance and efficiency when compared to traditional standard plastic-packaged components.
The AUIRF7739L2 in the large-can package delivers 0.7-mΩ RDS(on) at 40 V. The large package features a 60% smaller footprint and 85% lower profile than a D2PAK. The device suits heavy-load motor-control applications including electric power steering, battery switches, and integrated starter alternators in micro hybrid vehicles (stop and go), and chassis, drive train, and power train systems.
The AUIRF7665S2 small can device features 8.3-nC gate charge and exhibits low parasitics for fast switching performance. This device targets automotive switching applications including the output stage of Class D audio amplifiers as well as dc/dc converters and fuel injection systems. (Ea/low volume: AUIRF7739L2, $2.60; AUIRF7665S2, $0.46 available now.)
