The basic equation for heat transfer or power dissipation may be stated as follows:
Where:
PD = the power dissipated by the semiconductor device in watts.
ΔT = the temperature difference of driving potential which causes the flow of heat.
ΣRθ = the sum of the thermal resistances of the heat flow path across which ΔT exists.
The above relationship may be stated in the following forms:
The above equations are generally used to determine the required thermal resistance of the heat sink (RθSA),
since the heat dissipation, maximum junction and/or case temperature, and ambient temperature are known or set.
How To Select a Heat Sink
Where:
TJ = the junction temperature in °C (maximum is usually stated by the manufacturer of the semiconductor device).
TC = case temperature of the semiconductor device in °C.
TS = temperature of the heat sink mounting surface in thermal contact with the semiconductor device in °C.
TA = ambient air temperature in °C.
RθJC = thermal resistance from junction to case of the semiconductor device in °C per watt
(usually stated by manufacturer of semiconductor device).
RθCS = thermal resistance through the interface between the semiconductor device
and the surface on which it is mounted in °C per watt.
RθSA = thermal resistance from mounting surface to ambient or thermal resistance of heat sink in °C per watt.
Figure 1 indicates the location of the various heat
flow paths, temperatures and thermal resistances.
The common practice is to represent the system with
a network of resistances in series as shown in Figure 2.
