MOUNTING INSTRUCTION
The power dissipated in the circuit must be removed
by adding an external heatsink.
Thanks to the Heptawatt package attaching the
hetsink is very simple, a screw or a compression
spring (clip) being sufficient. Between the heatsink
Figure 32. Mounting example
and the package it is better to insert a layer of silicon
grease, to optimize the thermal contact, no electri-
cal isolation is needed between the two surfaces.
