Package thermal characteristics
Using a double-layer PCB the thermal resistance, junction to ambient, with 2 copper ground
areas of 3 x 3 cm2 and with 16 via holes is 24 °C/W in natural air convection.
The dissipated power within the device depends primarily on the supply voltage, load
impedance and output modulation level.
Thus, the maximum estimated dissipated power for the STA339BWS is:
Figure 23 shows the power derating curve for the PowerSSO-36 package on PCBs with
copper areas of 2 x 2 cm2 and 3 x 3 cm2.
