For a given θ_JA (listed in the Electrical
Characteristics), the maximum power dissipation is
shown in Figure 20 and calculated by Equation 2:
P_D = ^{TMAX - TA}
( ) _qJA
(2)
Where:
P_D = maximum power dissipation (W)
T_MAX = absolute maximum junction temperature
(+125°C)
T_A = free-ambient air temperature (°C)
