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 Fig. 10. Note that the airflow is parallel
to the long axis of the module as shown in Fig. 10.

The thermal reference point, T
ref
used in the
specifications is shown in Figure 11. For reliable
operation this temperature should not exceed 125
o
C.
The output power of the module should not exceed
the rated output current of the module.
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.
