depend on the external system (PCB, case) characteristics, and are under user responsibility.
The junction temperature can be calculated using the following equation:
the total thermal resistance between the junction and the ambient. This total junction ambient resistance
can be obtained from the upper four partial thermal resistances, by
a) simply adding only the two thermal resistances (junction lead and lead ambient), or
b) by taking all four resistances into account, depending on the precision needed.
