Heat Transfer with Heat Sinks
The power modules have through-threaded, M3 x 0.5
mounting holes, which enable heat sinks or cold plates
to attach to the module. The mounting torque must not
exceed 0.56 N-m (5 in.-lb.).
Thermal derating with heat sinks is expressed by using
the overall thermal resistance of the module. Total
module thermal resistance (
θ
ca) is defined as the max-
imum case temperature rise (
T
C, max
) divided by the
module power dissipation (P
D
):
The location to measure case temperature (T
C
) is
shown in Figure 20. Case-to-ambient thermal resis-
tance vs. airflow is shown, for various heat sink config-
urations and heights, in Figure 24. These curves were
obtained by experimental testing of heat sinks, which
are offered in the product catalog.
