MOUNTING INSTRUCTIONS The power dissipated in the circuit must be removed by adding an external heatsink. Thanks to the HEPTAWATTTM package attaching the heatsink is very simple, a screw or a compression 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 connected to Pin 4 which is ground.
