Description
The AUIRF7647S2TR combines the latest Automotive HEXFET
®
Power MOSFET Silicon technology with the advanced DirectFET
®
packaging
platform to produce a best in class part for Automotive Class D audio amplifier applications. 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 optimizes gate charge, body diode reverse recovery and internal gate resistance to improve key Class D audio
amplifier performance factors such as efficiency, THD and EMI. Moreover the DirectFET
®
packaging platform offers low parasitic inductance and
resistance when compared to conventional wire bonded SOIC packages which improves EMI performance by reducing the voltage ringing that
accompanies current transients. These features combine to make this MOSFET a highly desirable component in Automotive Class D audio amplifier
systems.
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 (TA) is 25°C, unless otherwise specified.
