Heatsink Design Considerations heatsink thermal resistance, c-a, required dissipate STK401-270 device total power dissipation, determined follows Condition substrate temperature exceed 125°C. Where guaranteed maximum ambient temperature. Condition Power transistor junction temperature, exceed 150°C. where number power transistors power transistor thermal resistance transistor. Note that power dissipated transistor total, divided evenly among power transistors. Expressions rewritten making subject. c-a< (125-Ta)/Pd (1)' c-a< (150-Ta)/Pd-j-c/N (2)' heatsink required must have thermal resistance that simultaneously satisfies both expressions. heatsink thermal resistance determined from (1)' (2)' once following parameters have been defined. Supply voltage Load resistance Guaranteed maximum ambient temperature
total device power dissipation when STK401-270 VCC=±30V RL=6, continuous sine wave signal, maximum 62.5W, shown Pd-PO graphs. When estimating power dissipation actual audio signal input, rule thumb select corresponding (1/10) (within safe limits) continuous sine wave input. example, Pd=38W [for (1/10) max=4W] STK401-270 power transistors, thermal resistance transistor, j-c, 1.7°C/W. guaranteed maximum ambient temperature, 50°C, then required heatsink thermal resistance, c-a, From expression (1)' (125-50)/38 1.97 From expression (2)' (150-50)/38-1.7/4 2.20 Therefore, satisfy both expressions, required heatsink must have thermal resistance less than 1.97°C/W. Similarly, when STK401-270 VCC=±24V RL=3, Pd=43W [for (1/10) max=4W] From expression (1)' (125-50)/43 1.74 From expression (2)' (150-50)/43-1.7/4 1.90 Therefore, satisfy both expressions, required heatsink must have thermal resistance less than 1.74°C/W. This heatsink design example based constant-voltage supply, should verified within your specific environment.
