Note :
1. For SOT-89 package, Thermal Resistance-Junction to Tab ( θJT ) =35OC/W. TJ = TTAB + (PD x θJT)
2.
θJA: Thermal Resistance-Junction to Ambient
Junction Temperature Calculation: TJ = TA + (PD x θJA).
The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
All of the above assume no ambient airflow.
