Note :
1. θ_JA: Thermal Resistance-Junction to Ambient, D_F : Derating factor, Po: Power consumption.
Junction Temperature Calculation: T_J = T_A + (P_D × θ_JA), Po = D_F × ( Tj- 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 Tab, T_C: case(Tab) temperature, T_J = T_C + (P_D × θ_JT)
For P and DD packages, θ_JT = 3.0 ^OC / W.
3. If power consumption is over above rating, adequate heat sink is required to dissipate heat.
