Note: T_J = T_A + (P_D × θ_JA)
P_D: Power dissipation.
θ_JA: Thermal resistance from Junction to Ambient.
For PK package, θ_JT = 35^O C / W.
T_J = T_TAB + (P_D × θ_JT)
T_TAB: Tab temperature.
θ_JT: Thermal resistance from junction to tab of the package.
The θ_JA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
