Thermal Considerations (continued)
Forced Convection Cooling
To determine the necessary airflow, determine the
power dissipated by the unit for the particular applica-
tion for these power modules over a range of output
currents. With the known power dissipation and a given
local ambient temperature, the appropriate airflow can
be chosen from the derating curves in Figure 24. For
example, if the unit dissipates 6.2 W, the minimum air-
flow in a 80 °C environment is 1.0 ms–1 (200 ft./min).
