5 / 10 page May 1992 5 Philips Semiconductors Product specification 50 W high performance hi-fi amplifier TDA1514A The theoretical maximum power dissipation for Po = 40 W with a stabilized power supply is: where VP = ± 27.5 V; RL =8 Ω Considering, for example, a maximum ambient temperature of 50 °C and a maximum junction temperature of 150 °C the total thermal resistance is: Since the thermal resistance of the SOT131A encapsulation is Rth j-mb < 1 K/W, the thermal resistance required of the heatsink is Rth h-a < 4.3 K/W. SAFE OPERATING AREA (SOAR) PROTECTION V 2 P 2 π 2 R L ----------------- 19 W; = R th j-a 150 50 – 19 ---------------------- 5.3 K/W == Fig.3 SOAR protection curve. |
