Thermal Considerations
Power modules operate in a variety of thermal
environments; however, sufficient cooling should always
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
29. Note that the airflow is parallel to the short axis of the
module as shown in Figure 30. The derating data applies
to airflow in either direction of the module’s short axis.

The
specifications is shown in Figure 30. For reliable
operation the temperatures at this point should not
exceed 125
not exceed the rated power of the module (Vo,set x
Io,max).

Mounted Power Modules” for a detailed discussion of
thermal aspects including maximum device temperatures.
