DS9069-09 November 2018 RT9069 Application Information Thermal Considerations The maximum power dissipation depends on the For continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : operating ambient temperature for fixed TJ(MAX) and where TJ(MAX) is the maximum junction temperature, TA is the ambient temperature, and JA is the junction to ambient thermal resistance. For recommended operating condition specifications, the maximum junction temperature is 125C. The junction to ambient thermal resistance, JA, is layout dependent. For SOP-8 (Exposed Pad) packages, the thermal resistance, JA, is 30.6C/W on a standard JEDEC 51-7 four-layer thermal test board. For SOT-23-5 package, the thermal resistance, JA, is 218.1C/W on a standard JEDEC 51-7 four-layer thermal test board. For SOT-89-5 package, the thermal resistance, JA, is 113.9C/W on a standard JEDEC 51-7 four-layer thermal test board. For UDFN-6L 1.6x1.6 package, the thermal resistance, JA, is 46.5C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at allows the designer to see the effect of rising ambient temperature on the maximum power dissipation 4.0 Maximum Power Dissipation (W)1 PD(MAX) = (TJ(MAX)  TA) / JA thermal resistance, JA.
