The temperature is monitored at the package back-side interface (Tcase) as shown below. The system maximum temperature must be adjusted i n 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 cannot be maintained below than the maximum temperature specified (see the curve Pdiss. Max) in order to guarantee the nominal device life time (MTTF). Recommended max. junction temperature (Tj max) : 134 °C Junction temperature absolute maximum rating : 175 °C Max. continuous dissipated power (Pdiss. Max.) : 0.5 W => Pdiss. Max. derating above Tcase(1)= 85 °C : 10 mW/°C Junction-Case thermal resistance (Rth J-C)(2) : <103 °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.
