18 / 23 page ![]() Package thermal characteristics STA333ML 18/23 DocID13177 Rev 8 6 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 (see Figure 13) 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. The max estimated dissipated power for the is: Figure 13. Double layer PCB with 2 copper ground areas and 16 via holes Figure 14 shows the power derating curve for the PowerSSO-36 package on a board with two copper areas of 2 x 2 cm2 and 3 x 3 cm2. Figure 14. PowerSSO-36 power derating curve 2 x 20 W into 8 , at 18 V Pd max is approximately 4 W 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 Pd (W) Tamb ( °C) Copper Area 2x2 cm and via holes STA333BW PSSO36 Copper Area 3x3 cm and via holes 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 Pd (W) Tamb ( °C) Copper Area 2x2 cm and via holes STA333ML PSSO36 Copper Area 3x3 cm and via holes 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 Pd (W) Tamb ( °C) Copper Area 2x2 cm and via holes STA333BW PSSO36 Copper Area 3x3 cm and via holes 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 20 40 60 80 100 120 140 160 Pd (W) Tamb ( °C) Copper Area 2x2 cm and via holes STA333BW PSSO36 Copper Area 3x3 cm and via holes 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 0 1 2 3 4 5 6 7 8 0 20 40 60 80 100 120 140 160 Pd (W) Tamb ( °C) Copper Area 2x2 cm and via holes STA333ML PSSO36 Copper Area 3x3 cm and via holes STA333ML PowerSSO-36 |
