Description
The AUIRF7737L2 combines the latest Automotive HEXFET® Power MOSFET Silicon technology with the advanced DirectFET® packaging
technology to achieve exceptional performance in a package that has the footprint of a DPak (TO-252AA) and only 0.7 mm profile. The
DirectFET® package is compatible with existing layout geometries used in power applications, PCB assembly equipment and vapor phase, infra-
red or convection soldering techniques, when application note AN-1035 is followed regarding the manufacturing methods and processes. The
DirectFET® package allows dual sided cooling to maximize thermal transfer in automotive power systems.
This HEXFET® Power MOSFET is designed for applications where efficiency and power density are of value. The advanced DirectFET® packaging
platform coupled with the latest silicon technology allows the AUIRF7737L2 to offer substantial system level savings and performance improvement
specifically in motor drive, high frequency DC-DC and other heavy load applications on ICE, HEV and EV platforms. This MOSFET utilizes the latest
processing techniques to achieve low on-resistance and low Qg per silicon area. Additional features of this MOSFET are 175°C operating junction
temperature and high repetitive peak current capability. These features combine to make this MOSFET a highly efficient, robust and reliable
device for high current automotive applications.
Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the specifications is not implied.Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions. Ambient temperature (T_A) is 25°C, unless otherwise specified.
