Automotive DirectFET2 power MOSFETs offer power density and performance benefits

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

The first automotive DirectFET2 devices from IR are entirely lead-free and offer overall system level size and cost reductions along with performance and efficiency benefits when compared with traditional standard plastic packaged components.

“The new DirectFET2 devices may be optimized by application for next-generation vehicle platforms for ultra-low on-state resistance (RDS(on)), gate charge (Qg) or logic level operation to deliver dramatically improved performance and efficiency, and reduced system size and part count,” said Benjamin Jackson, product manager, Automotive Products Business Unit.

The AUIRF7739L2 in the new large can package claims to deliver the industry's lowest RDS(on) of 0.7mOhm (typical) at 40 V in a given PCB area. Moreover, the large can features a 60 percent smaller footprint and 85 percent lower profile than a D2PAK. The device offers power density and efficiency benefits making it well suited to heavy load motor control applications including Electric Power Steering (EPS), battery switches and Integrated Starter Alternators (ISA) in Micro Hybrid Vehicles, and chassis, drive train and power train systems.

The AUIRF7665S2 small can device is optimized for low gate charge and exhibits 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.

Both devices are qualified according to AEC-Q101 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials, and are part of IR's automotive quality initiative targeting zero defects.

Availability and Pricing

Pricing for the AUIRF7739L2 and the AUIRF7665S2 begins at US $2.60 each and US $0.46 each respectively in low volume quantities. Production orders are available immediately.
