Clipwatt mounting suggestions

The suggested method for securing the Clipwatt package on an external heat sink is by a

spring clip placed as close as possible to the center of the plastic body, as indicated in the

example of Figure 26.

Thermal grease can be used to further reduce the thermal resistance of the contact

between package and heatsink.

The clip should apply a force of 7 - 10 kg to provide sufficient pressure for a good contact.

Care must be taken to ensure that the contact pressure on the package does not exceed

15 kg/mm².

As an example, if the clip applies a 15-kg force on the package then the clip must have a

contact area of at least 1 mm².
