Description

This Digital Audio HEXFET

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.
