General Notes for Specifications at Maximum Junction Temperature
An estimation of the device junction temperature, T
J, can be obtained from the equation:
TJ = TA + (RJA PD)
where:
TA = ambient temperature for the package (oC)
RJA = junction to ambient thermal resistance (oC/W)
PD = power dissipation in the package (W)
The thermal resistance values used are based on the JEDEC JESD51 series of standards to provide
consistent values for estimations and comparisons. The difference between the values determined for the
single-layer (1s) board compared to a four-layer board that has two signal layers, a power and a ground
plane (2s2p), demonstrate that the effective thermal resistance is not a constant. The thermal resistance
depends on the:
Construction of the application board (number of planes)
Effective size of the board which cools the component
Quality of the thermal and electrical connections to the planes
Power dissipated by adjacent components
Connect all the ground and power balls to the respective planes with one via per ball. Using fewer vias to
connect the package to the planes reduces the thermal performance. Thinner planes also reduce the thermal
performance. When the clearance between the vias leave the planes virtually disconnected, the thermal
performance is also greatly reduced.
As a general rule, the value obtained on a single-layer board is within the normal range for the tightly
packed printed circuit board. The value obtained on a board with the internal planes is usually within the
normal range if the application board has:
One oz. (35 micron nominal thickness) internal planes
Components are well separated
Overall power dissipation on the board is less than 0.02 W/cm2
The thermal performance of any component depends on the power dissipation of the surrounding
components. In addition, the ambient temperature varies widely within the application. For many natural
convection and especially closed box applications, the board temperature at the perimeter (edge) of the
package is approximately the same as the local air temperature near the device. Specifying the local
ambient conditions explicitly as the board temperature provides a more precise description of the local
ambient conditions that determine the temperature of the device.
3 Per JEDEC JESD51-6 with the board horizontal.
4 Thermal resistance between the die and the printed circuit board per JEDEC JESD51-8. Board temperature is measured on
the top surface of the board near the package.
5 Indicates the average thermal resistance between the die and the case top surface as measured by the cold plate method
(MIL SPEC-883 Method 1012.1) with the cold plate temperature used for the case temperature.
6 Thermal characterization parameter indicating the temperature difference between package top and the junction temperature
per JEDEC JESD51-2.
