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.

Purely a thermal phenomenon and failure occurs at a temperature far in
excess of T

. This is validated for every part type.
2. Safe operation in Avalanche is allowed as long as T
