the derating curve. For improved design
margins and enhanced system reliability, the
power module may be operated at
temperatures below the maximum rated
operating temperature.
Heat transfer by convection can be
enhanced by increasing the airflow rate that
the power module experiences. The
maximum output current of the power
module is a function of ambient temperature
(T
AMB
) and airflow rate as shown in the
thermal performance figures on the thermal
performance page for the power module of
interest. The curve in the figures is shown
for natural convection and up. The data for
the natural convection condition has been
collected at 0.3 m/s (60 ft/min) of airflow,
which is the typical airflow generated by
other heat dissipating components in many
of the systems that these types of modules
are used in. In the final system
configurations, the airflow rate for the natural
convection condition can vary due to
temperature gradients from other heat
dissipating components.
