Orientation 2
For example, if the LUW025A dissipates 3 W of heat at
2.7 A load, the minimum airflow for Orientation 1 in a
80 °C environment is 1.0 m/s (200 ft./min.).
Keep in mind that these derating curves are approxi-
mations of the ambient temperatures and airflows
required to keep the power module temperature below
its maximum rating. Once the module is assembled in
the actual system, the module’s temperature should be
checked as shown in Figures 17—18 to ensure it does
not exceed 110 °C.
