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 below.
