MOUNTING INSTRUCTION
The R
th j-amb
of the L6221AS can be reduced by sol-
dering the GND pins to a suitable copper area of the
printed circuit board (Fig. 23) or to an external
heatsink (Fig. 24).
The diagram of figure 25 shows the maximum dis-
sipable power P
tot
and the R
th j-amb
as a function of
the side "
α
" of two equal square copper areas hav-
ing a thickness of 35
μ
(1.4 mils). During soldering
the pins temperature must not exceed 260
°
C and
the soldering time must not be longer than 12 sec-
onds.
The external heatsink or printed circuit copper area
must be connected to electrical ground.
