Power Mosfets for automotive applications

The Mosfets are also ideal for high-intensity discharge (HID) lighting and other automotive power conversion applications.

The AUIRF7648M2 and AUIRF7669L2, International Rectifier's first automotive-grade DirectFET devices tailored to DC/DC applications, offer low gate charge and on-state resistance (RDS(on)) to help minimise switching and conduction losses in a variety of switching applications.

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

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

With package current ratings of 179A and 375A respectively for each device, 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, feature an environmentally friendly, lead-free and RoHS-compliant bill of materials, and are part of International Rectifier's automotive quality initiative targeting zero defects.
