Continuous operation above the recommended junction temperature may result in reduced reliability and/or lifetime of the device. The junction
temperature is controlled by the thermal design of the application and should be carefully considered in high power dissipation applications. See
the thermal considerations section on pages 33−35 for recommendations on improving the thermal performance of your application.
