MOUNTING INSTRUCTION
The junction to ambient thermal resistance of the
TDA 1170S can be reduced by soldering the tabs
to a suitable copper area of the printed circuit board
(fig. 4) or to an external heatsink (fig. 5).
Figure 4 : Example of P.C Board Copper Are
is Used as Heatsink
The diagram of fig. 6 shows the maximum dissipa-
ble power Ptot and the Rth j-amb as a function of the
side ”s” of two equal square copper areas having
a thickness of 35 µ (1.4 mil).
