CLIPWATT ASSEMBLING SUGGESTIONS
The suggested mounting method of Clipwatt on external heat sink, requires the use of a clip placed as much as
possible in the plastic body center, as indicated in the example of figure 21.
A thermal grease can be used in order to reduce the additional thermal resistance of the contact between pack-
age and heatsink.
A pressing force of 7 - 10 Kg gives a good contact and the clip must be designed in order to avoid a maximum
contact pressure of 15 Kg/mm2 between it and the plastic body case.
As example, if a 15Kg force is applied by the clip on the package, the clip must have a contact area of 1mm2
at least.
