MOUNTING INSTRUCTIONS
The power dissipated in the circuit must be re-
moved by adding an external heatsink.
Thanks to the HEPTAWATT^TM package attaching
the heatsink is very simple, a screw a compression

spring (clip) being sufficient. Between the heatsink
and the packageit isbetter to insert a layerof silicon
grease, to optimize the thermal contact ; no electri-
cal isolation is needed between the two surfaces.
