From the formula (1) and (2), we will obtain: θc-a < (125 − Ta)/Pd·····························································································(1)’ θc-a < (150 − Ta)/Pd − θj-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 STK433-890N-E ; 50W×4ch) If VCC is ±34V, and RL is 6Ω, then the total power dissipation (Pd) of inside Hybrid IC is as follow; Pd = 99.0W (at 6.25W output power,1/8 of PO max) There are eight (8) transistors in Audio Section of this Hybrid IC, and thermal resistance (θj-c) of each transistor is 2.1°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)’ θc-a < (125 − 50)/99.0 < 0.76 From (2)’ θc-a < (150 − 50)/99.0 − 2.1/8 < 0.75 Therefore, in order to satisfy both (1)’ and (2)’, the thermal resistance of a desired Heat-sink will be 0.75°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.
