The temperature is monitored at the package back-side interface (Tcase) as shown below. The system maximum temperature must be adjusted in order to guarantee that Tcase remains below than the maximum value specified in the next table. So, the system PCB must be designed to comply with this requirement. A derating must be applied on the dissipated power if the Tcase temperature can not be maintained below than the maximum temperature specified in order to guarantee the nominal device life time (MTTF) (see the curve Pdiss. Max below). Recommended max. junction temperature (Tj max) : 164 °C Junction temperature absolute maximum rating : 175 °C Max. continuous dissipated power (Pdiss. Max.) : 1.5 W => Pdiss. Max. derating above Tcase(1)= 85 °C : 19 mW/°C Junction-Case thermal resistance (Rth J-C)(2) : <51 °C/W Minimum Tcase operating temperature(3) : -40 °C Maximum Tcase operating temperature(3) : 85 °C Minimum storage temperature : -55 °C Maximum storage temperature : 150 °C (1 ) Derating at junction temperature constant = Tj max. (2) Rth J-C is calculated for a worst case considering the ho ttest junctio n of the M M IC and all the devices biased.

ESD protections are also implemented on gate accesses. The DC connections do not include any decoupling capacitor in package, therefore it is mandatory to provide a good external DC decoupling on the PC board, as close as possible to the package.
