Description
This Digital Audio HEXFET® 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. Additional features of this MosFET are 175°C operating junction temperature and repetitive avalanche capability.
These features combine to make this MosFET a highly efficient, robust and reliable device for Class-D audio amplifier
applications.
