International Rectifier announces the expansion of its family of automotive DirectFET2 power MOSFETs.

International Rectifier announces the expansion of its family of automotive DirectFET2 power MOSFETs. These devices deliver high power density, dual-sided cooling, and minimal parasitic inductance and resistance for heavy load applications, including Electric Power Steering (EPS), power supplies, battery switches on hybrid electric vehicles, and Integrated Starter Alternators (ISA) on micro hybrid vehicles.

The automotive-qualified DirectFET2 devices offer overall system level size and cost reductions along with superior performance and efficiency when compared to traditional standard plastic packaged components, according to company sources. Featuring a PCB footprint 60% smaller than a D2Pak, the AUIRF7738L2 and AUIRF7737L2 DirectFET2 devices deliver exceptionally low on-state resistance (RDS(on)), while the AUIRF7736M2 features a PCB footprint the same size as a 5x6 mm PQFN or SO-8 package with low RDS(on) of 2.5 mOhm, making it suitable for more cost sensitive, lower power applications.

The AUIRF7737L2 and AUIRF7738L2 share a common Large Can PCB footprint with the previously released AUIRF7739L2, making the devices desirable components where a scalable system design is required. With a package current rating of 315 A for both devices, the DirectFET package places no constraint on current capability of the silicon. Moreover, the maximum package current ratings exceed the limits of traditional DPak and D2Pak packages. The devices are qualified according to AEC-Q101 standards and feature an environmentally friendly, lead-free, and RoHS compliant bill of materials.
