STK404-070N-E no.a2105-8/10 a thermal design tip for STK404-070N-E amplifier [thermal design conditions] the thermal resistance ( c-a) of the heat-sink which manages the heat dissipation inside the hybrid ic will be determined as follow: (condition 1) the case temperature (tc) of the hybrid ic should not exceed 125c pd ? ? c-a + ta ? 125c (1) where ta : the ambient te mperature for the system (condition 2) the junction temperature of e ach power transistor should not exceed 150c pd ? ? c-a + pd/n ? ? j-c + ta ? 150c (2) where n : the number of transistors (two for 1 channel , ten for channel) j-c : the thermal resistance of each transistor (see specification) note that the power consumption of each power transistor is assumed to be equal to the total power dissipation (pd) divided by the number of transistors (n). 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)? w ill be the thermal resistance for a desired heat-sink. note that all of the component except power transistors employed in the hybr id 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 p o max. (note that the value of 1/8 p o max may be varied from the country to country.) (sample of STK404-070N-E ; 40w1ch) if v cc is 30v, and r l 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 p o max) there are two (2) transistors in audio section of this hybrid ic, and thermal resistance ( j-c) of each transistor is 3.0c/w. if the ambient temperature (ta) is gu aranteed for 50c, then the thermal resistance ( c-a) of a desired heat- sink 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 th ermal resistance of a desired heat-sink will be 3.60c/w. [note] above are reference only. the samples ar e operated with a constant power suppl y. please verify the conditions when your system is actually implemented.
