Data Sheet
October 1, 2009
Power modules operate in a variety of thermal
environments; however, sufficient cooling should be
provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of the
module will result in an increase in reliability. The thermal
data presented here is based on physical measurements
taken in a wind tunnel. The test set-up is shown in Figure
32. Note that the airflow is parallel to the long axis of the
module as shown in figure 31. The derating data applies
to airflow in either direction of the module’s long axis.
Figure 31. T ref Temperature measurement location.
The thermal reference points, T
specifications of thermal derating curves are shown in
Figure 31. For reliable operation these temperatures
should not exceed 125
The output power of the module should not exceed the
rated power of the module (Vo,set x Io,max).
Please refer to the Application Note “Thermal
Characterization Process For Open-Frame Board-
Mounted Power Modules” for a detailed discussion of
thermal aspects including maximum device temperatures.

Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Thermal derating curves showing
the maximum output current that can be delivered by
various module versus local ambient temperature (T

in the Characteristics Curves section.
Layout Considerations
Copper paths must not be routed beneath the power
module. For additional layout guide-lines, refer to
