Note 1: The maximum allowable power dissipation is a function of ambient temperature, the maximum allowable
junction temperature and the thermal resistance from junction to air (i.e., T
A
, T
J
, 
JA
). Exceeding the
maximum allowable power dissipation causes the device operating junction temperature to exceed the
maximum +150°C rating. Sustained junction temperatures above +150°C can impact the device reliability.
