Although the previous example uses 100 °C as the
maximum case temperature, for extremely high reliabil-
ity applications, one can use a lower temperature for
T
It is important to point out that the thermal resistances
shown in Figure 35 are for heat transfer from the sides
and bottom of the module as well as the top side with
the attached heat sink; therefore, the case-to-ambient
thermal resistances shown will generally be lower than
the resistance of the heat sink by itself. The data in Fig-
ure 35 was taken with a thermally conductive dry pad
between the case and the heat sink to minimize contact
resistance (typically 0.1 °C/W to 0.3 °C/W).
For a more detailed explanation of thermal energy
management for this series of power modules as well
as more details on available heat sinks, please request

Layout Considerations
Copper paths must not be routed beneath the power
module standoffs.
