Mounting Instructions
The power dissipated in the circuit is removed by adding an external heatsink. With the
HEPTAWATT™ package, the heatsink is simply attached with a screw or a compression spring
(clip).
A layer of silicon grease inserted between heatsink and package optimizes thermal contact. In DC-
coupled applications we recommend to use a silicone tape between the device tab and the heatsink
to electrically isolate the tab.
