MOUNTING INSTRUCTIONS
The power dissipated in the circuit must be re-
moved by adding an external heatsink.
Thanks to the HEPTAWATTTM package attaching
the heatsink is very simple, a screw or a compres-
sion spring (clip) being sufficient.
Figure 3 : Mounting Examples
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 con-
nected to Pin 4 which is ground.
