315 Amp power MOSFETs from IR for hybrid automotives
International Rectifier (IR) has unveiled new automotive DirectFET2 power MOSFETs suitable for heavy load applications such as Electric Power Steering (EPS), power supplies, battery switches on hybrid electric vehicles and Integrated Starter Alternators (ISA) on micro hybrid vehicles.
IR says the AEC-Q101 qualified DirectFET2 devices features 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 2.5mOhm, making it suitable for more cost sensitive lower power applications.
"Utilizing IR's advanced Trench silicon process, the expansion of our DirectFET2 portfolio offers automotive systems designers the proven benefits of exceptional power density, dual-sided cooling and low parasitic package inductance and resistance in a robust, reliable and scalable power package," said Benjamin Jackson, product manager, IR's Automotive Products Business Unit.
IR says the AUIRF7737L2 and AUIRF7738L2 share a common Large Can PCB footprint with the previously released AUIRF7739L2 making the devices highly 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 far exceed the limits of traditional DPak and D2Pak packages, claims IR.
The devices are qualified according to AEC-Q101 standards and is lead-free and RoHS compliant.
