Rth j-a from junction to ambient in free air TDA7052A 100 K/W TDA7052AT 155 K/W
Notes to the thermal resistance
TDA7052A: VP = 6 V; RL = 8 Ω. The maximum sine-wave dissipation is 0.9 W. Therefore Tamb(max) = 150 − 100 × 0.9 = 60 °C. TDA7052AT: VP = 6 V; RL = 16 Ω. The maximum sine-wave dissipation is 0.46 W. Therefore Tamb(max) = 150 − 155 × 0.46 = 78 °C.
