Thermal resistance θc-a of a heat sink must satisfy ine-
qualities (1) and (3).
Figure 2 shows the relation between Pd and θc-a given
from (1) and (3) with Ta as a parameter.
[Example] The thermal resistance of a heat sink is
obtained when the ambient temperature speci-
fied for a stereo amplifier is 50°C.
Assuming VCC = 44V, RL = 8Ω,
RL = 8Ω : Pd = 17.2W at 1/10 Po max.
The thermal resistance of a heat sink is
obtained from Figure 2.
RL = 8Ω : θc-a = 4.36°C/W
Tj when a heat sink is used is obtained from
(3).
RL = 8Ω : Tj = 140.5°C
IC Power dissipation, Pd - W
