Thermal Measurements
The derating curves in Figure 16 were derived from measurements obtained in an experimental apparatus shown
in Figure 21. Note that the module and the printed-wiring board (PWB) that it is mounted on are vertically oriented.
The passage has a rectangular cross section.
Note: Dimensions are in millimeters and (inches)
Layout Considerations
Copper paths must not be routed beneath the power module standoffs.
