From the formula (1) and (2), we will obtain: c-a  (125  Ta)/Pd ······································································ (1)’ c-a  (150  Ta)/Pd  j-c/N ··························································· (2)’ The value which satisfies above formula (1)’ and (2)’ will be the thermal resistance for a desired heat-sink. Note that all of the component except power transistors employed in the Hybrid IC comply with above conditions. [Example of Thermal Design] Generally, the power consumption of actual music signals are being estimated by the continuous signal of 1/8 PO max. (Note that the value of 1/8 PO max may be varied from the country to country.) (Sample of STK404-070N-E ; 40W×1ch) If VCC is ±30V, and RL is 6, then the total power dissipation (Pd) of inside Hybrid IC is as follow; Pd = 19.6W (at 5W output power,1/8 of PO max) There are two (2) transistors in Audio Section of this Hybrid IC, and thermal resistance (θj-c) of each transistor is 3.0°C/W. If the ambient temperature (Ta) is guaranteed for 50°C, then the thermal resistance (θc-a) of a desired heatsink should be; From (1)’ c-a  (125  50)/19.6  3.83 From (2)’ c-a  (150  50)/19.6  3.0/2  3.60 Therefore, in order to satisfy both (1)’ and (2)’, the thermal resistance of a desired Heat-sink will be 3.60°C/W. [Note] Above are reference only. The samples are operated with a constant power supply. Please verify the conditions when your system is actually implemented.
