THERMAL INFORMATION:
The power dissipated within the device depends primarly on the supply voltage, load impedance and output
modulation level. The PSSO36 Package of the STA540P includes an exposed thermal slug on the top of the
device to provide a direct thermal path from the IC to the heatsink.
Considering that for the STA540P the Thermal resistance Junction to slug is 1.5°C/W and the extimated
Thermal resistance due to the grease placed between slug and heat sink is 2.3°C/W ( the use of thermal
pads for this package is not recommended), the suitable Heat Sink Rth to be used can be drawn from the
following graph fig 5, where is shown the Derating Power vs.Tambient for different heatsinkers.
