International Rectifier AUIRF7648M2 and AUIRF7669L2 power MOSFETs

International Rectifier has introduced two motor vehicle DirectFETR2 power MOSFETs optimised with low gate charge for switching applications including switch mode power supplies, class d audio systems, high intensity discharge lighting, and other power conversion applications.

The AUIRF7648M2 and AUIRF7669L2, the company’s first motor vehicle grade DirectFETR devices tailored to DC-DC applications, offer low gate charge and on-state resistance to help minimise switching and conduction losses in a variety of switching applications.

The low parasitic inductance offered by the DirectFETR power package results in good high-frequency switching with reduced waveform ringing, which helps limit EMI and filter size.

The AUIRF7648M2 features a PCB footprint 54% smaller than a DPak, while the AUIRF7669L2 features a PCB footprint 60% smaller than a D2Pak.

With package current ratings of 179 and 375 A for each device, the devices place no constraint on current capability of the silicon. Moreover, the maximum package current ratings far exceed the limits of traditional DPak and D2Pak packages.

The devices are qualified according to AEC-Q101 standards, feature an environmentally friendly, lead-free and RoHS-compliant bill of materials, and are part of the company’s motor vehicle quality initiative targeting zero defects.
