Heat Dissipation
An estimation of the chip-junction temperature, TJ, can be obtained from the following equation:
TJ =TA+(RθJA × PD)
Eqn. 1
where:
TA = ambient temperature for the package (°C)
RθJA = junction to ambient thermal resistance (°C/W)
PD = power dissipation in package (W)
The junction to ambient thermal resistance is an industry standard value, which 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 correct 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.

NOTES:
1
Junction temperature is a function of die size, on-chip power dissipation, package thermal resistance, mounting
site (board) temperature, ambient temperature, air flow, power dissipation of other components on the board, and
board thermal resistance.
