1) The thermal resistances between the case top and the ambient (R_TCAT), the leads and the ambient (R_TLA) are
to be combined with the thermal resistances between the junction and the case top (R_TJCT ), the junction and
the leads (R_TJL) given above, in order to calculate the total thermal resistance between the junction and the
ambient (R_TJA). The thermal resistances between the case top and the ambient (R_TCAT ), the leads and the
ambient (R_TLA) depend on the external system (PCB, case) characteristics, and are under user responsibility.
The junction temperature can be calculated using the following equation: T_J=T_A+R_TJA × P_D, where the R_TJA is
the total thermal resistance between the junction and the ambient. This total junction ambient resistance R_TJA
can be obtained from the upper four partial thermal resistances.
