11 / 15 page STA533WF Heatsink requirements Doc ID 17658 Rev 2 11/15 4 Heatsink requirements Using the STA533WF mounted on a double-layer PCB having 2 copper ground areas of 3x3cm2 and with 16 via holes the junction to ambient thermal resistance is approximately 24 °C/W in natural air convection. Figure 8. Double-layer PCB with copper ground areas and 16 via holes With the dissipated power within the device depending primarily on the supply voltage, the load impedance and the output modulation level, the maximum estimated dissipated power, Pdmax, for the STA533WF is: 4 W for 2 x 20 W into 8 Ω at 18 V < 5 W for 2 x 10 W into 8 Ω + 1 x 20 W into 4 Ω at 18 V. The figure below shows the power derating curve for the PowerSSO36 EPD package on PCBs with copper areas of 2 x 2 cm2 and 3 x 3 cm2. Figure 9.
