Note: TJ = TA + (PD × θJA)
PD: Power dissipation.
θJA: Thermal resistance from Junction to Ambient.
For T and ST/ST3 packages, θJT = 3.0 OC / W.
For SJ package, θJT = 7.0 OC /W.
TJ = TTAB + (PD × θJT)
TTAB: Tab temperature.
θJT: Thermal resistance from junction to tab of the package.
1. The θJA numbers are guidelines for the thermal performance of the device/PC-board system.
2. All of the above assume no ambient airflow.
3. If power consumption is over above rating, adequate heat sink is required to dissipate heat.
