thermal resistance from junction to

The thermal resistance depends strongly on the nature of the PCB used in the application
and on its design. The thermal resistance given in
can be measured on a multilayer PCB (4 layers) as defined by EIA/JESD51-2. This value
is given for information only.
The junction temperature influences strongly the reliability of an IC. The PCB used in the
application contributes on a large part to the overall thermal characteristic. It must
therefore be designed to insure that the junction temperature of the IC never exceeds
T
The IC has to be soldered to ground with its die-attached paddle. Plenty of vias are
recommended to remove the heat.
