Note:
1. Θ_JA : Thermal Resistance-Junction to Ambient, D_F: Derating factor, P_O: Power consumption.
Junction Temperature Calculation: T_J = T_A + (P_D x Θ_JA ), P_O = D_F x (T_J – T_A)
The Θ_JA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
2. Θ_JT : Thermal Resistance-Junction to Ambient, T_C: case (Tab) temperature, T_J = T_C + (P_D x Θ_JA )
