General notes for specifications at maximum junction temperature
TJ = TA + (RJA * PD)
Eqn. 1
where:
TA
= ambient temperature for the package (°C)
RJA
= junction to ambient thermal resistance (°C/W)
PD
= power dissipation in the package (W)
The junction to ambient thermal resistance is an industry standard value that provides a quick and easy estimation of thermal
performance. Unfortunately, there are two values in common usage: the value determined on a single layer board and the value
obtained on a board with two planes. For packages such as the PBGA, these values can be different by a factor of two. Which
value is closer to the application depends on the power dissipated by other components on the board. The value obtained on a
single layer board is appropriate for the tightly packed printed circuit board. The value obtained on the board with the internal
planes is usually appropriate if the board has low power dissipation and the components are well separated.
When a heat sink is used, the thermal resistance is expressed in Equation 2 as the sum of a junction to case thermal resistance
and a case to ambient thermal resistance:
RJA = RJC + RCA
Eqn. 2
where:
5 Thermal characterization parameter indicating the temperature difference between the case and the
junction temperature per JEDEC JESD51-2. When Greek letters are not available, the thermal
characterization parameter is written as Psi-JC.
