For a given q_JA, the maximum power dissipation is
shown in Figure 29, and is calculated by the following
formula:
ǒ Ǔ P_D +
T_MAX * T_A
q_JA
Where:
P_D = maximum power dissipation (W)
T_MAX = absolute maximum junction temperature (125°C)
T_A = free-ambient air temperature (°C)
q_JA = q_JC + q_CA
q_JC = thermal coefficient from junction to case (°C/W)
q_CA = thermal coefficient from case-to-ambient air (°C/W)
