and especially on the design of the printed-circuit board. The application mounting must be done in such a
way that the maximum junction temperature is never exceeded. An estimation of the junction temperature
can be obtained through measurement of the temperature of the top center of the package (T

Measured in free air as defined by JEDEC standard JESD51-2.
These values are given for information only. The thermal resistance depends strongly on the nature and
design of the printed-circuit board used in the application. The thermal resistance given corresponds to the
value that can be measured on a multilayer printed-circuit board (4 layers) as defined by JEDEC standard.
The junction temperature influences strongly the reliability of an IC. The printed-circuit board used in the
application contributes in a large part to the overall thermal characteristic. It must therefore be insured that
the junction temperature of the IC never exceeds T
