Thermal Considerations

Many conditions affect the thermal performance of the

power module, such as orientation, airflow over the module

and board spacing. To avoid exceeding the maximum

temperature rating of the components inside the power

module, the case temperature must be kept below 90°C.

The derating curves are determined from measurements

obtained in an experimental apparatus.
