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 IRF6643PbF device utilizes DirectFET® packaging technology. DirectFET® packaging technology offers lower parasitic
inductance and resistance when compared to conventional wirebonded SOIC packaging. Lower inductance improves EMI
performance by reducing the voltage ringing that accompanies fast current transients. 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 method and processes. The DirectFET® 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.
