Thermal Considerations
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 33. Note that the airflow is parallel to
the long axis of the module as shown in figure 32. The
derating data applies to airflow in either direction of the
module’s long axis.
The thermal reference points, T
specifications of thermal derating curves are shown in
Figure 32. 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).

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

section.
