Thanks to the HEPTAWATT TM 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 which is ground. 930H-08.EPS/930H-09.EPS /
