Thermal Considerations
The 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 thermal reference point, T
specifications is shown in Figure 29. For reliable
operation this temperature should not exceed 110
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. Derating figures showing the
maximum output current that can be delivered by various
module versus local ambient temperature (T
convection and up to 2m/s (400 ft./min) are shown in the
respective Characteristics Curves section.
Layout Considerations
The input capacitors should be located equal distance
from the two input pins of the module. Recommended
layout is shown in the mechanical section. In addition to
the input and output planes, a ground plane beneath the
module is recommended.
