Note: TJ = TA + (PD × θJA)
PD: Power dissipation.
θJA: Thermal resistance from Junction to Ambient.
For PK package, θJT = 35O C / W.
TJ = TTAB + (PD × θJT)
TTAB: Tab temperature.
θJT: Thermal resistance from junction to tab of the package.
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
