1. T_J is calculated from the ambient temperature T_A and the power dissipation P_D according the following formula:
T_J = T_A + (P_D x R_thJA). See Figure 16. for details of max power dissipation for ambient temperatures higher than 25 °C.
Note:
Absolute maximum ratings are those values beyond which damage to the device may occur.
Functional operation under these conditions is not implied.
