MOUNTINGINSTRUCTIONS

The power dissipated in the circuit must be re­moved by adding an external heatsink.
Thanks to the HEPTAWATT

package attaching
the heatsinkis very simple, a screwor a compres­sion spring(clip)being sufficient.

Between the heatsink and the package it is better
to insert a layer of silicon grease, to optimize the
thermal contact ; no electrical isolation is needed
between the two surfaces, since the tab is con­nectedto Pin 4 whichis ground.
