Philips Semiconductors Product specification 5 W audio power amplifier TDA2611A Fig.2 Power derating curves. HEATSINK EXAMPLE Assume V = 18 V; R = 8 Ω; T = 60 °C maximum; T = 150 °C (max. for a 4 W application into an 8 Ω load, the P L amb j maximum dissipation is about 2,2 W). The thermal resistance from junction to ambient can be expressed as: 150 – 60 R = R ++ R R== --------------------- - 41 K/W. th j-a th j-tab th tab-h th h-a 22 , Since R = 11 K/W and R = 1 K/W, R = 41 - (11 + 1) = 29 K/W.
