Note :1.For PK package, Thermal Resistance-Junction to Tab ( θJT ) = 35°C /W. TJ = TTAB + (PD à θJT).
PD: Power Dissipation.
2.θJA: Thermal Resistance-Junction to Ambient, DF = 1/θJA
Junction Temperature Calculation: TJ = TA + (PD à θJA).
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
