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).

The diagram of fig. 6 shows the maximum dissipa-
ble power P

and the R

th j-amb

as a function of the

side "s" of two equal square copper areas having
a thickness of 35
