Description
This Digital Audio MOSFET is specifically designed for Class-D audio amplifier applications. This MOSFET utilizes the
latest processing techniques to achieve low on-resistance per silicon area. Furthermore, gate charge, body-diode reverse
recovery and internal gate resistance are optimized to improve key Class-D audio amplifier performance factors such as
efficiency, THD, and EMI.
The IRF7665S2TR/TR1PbF device utilizes DirectFETTM packaging technology. DirectFETTM packaging technology offers lower
parasitic inductance and resistance when compared to conventional wirebonded SOIC packaging. Lower inductance im-
proves EMI performance by reducing the voltage ringing that accompanies fast current transients. The DirectFETTM 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 method and
processes. The DirectFETTM package also allows dual sided cooling to maximize thermal transfer in power systems, improving
thermal resistance and power dissipation. These features combine to make this MOSFET a highly efficient, robust and reliable
device for Class-D audio amplifier applications.
