Automotive power MOSFETs

3 March 2010 Power Electronics / Power Management

International Rectifier recently introduced the AUIRF7739L2 and AUIRF7665S2 DirectFET2 power MOSFETs that deliver high power density, dual-sided cooling and low parasitic inductance and resistance in a robust, reliable and AEC-Q101 qualified package for automotive applications.

The AUIRF7739L2 in the new large can package delivers low RDS(on) of 0,7 m at 40 V. This package features a 60% smaller footprint and 85% lower profile than a D2PAK. The device offers high power density and efficiency, making it well suited to heavy load motor control applications including electric power steering, battery switches and integrated starter alternators in micro hybrid vehicles, and chassis, drive train and power train systems.

The AUIRF7665S2 small can device is optimised for very low gate charge and exhibits low parasitics for fast and efficient switching performance. It is suitable for automotive switching applications including the output stage of Class D audio amplifiers as well as DC-DC converters and fuel injection systems.

Both devices are qualified according to AEC-Q101 standards and feature an environmentally friendly, lead-free and RoHS compliant bill of materials.
