MOUNTING INSTRUCTION
The Rth (j-a) can be reduced by soldering the GND
pins to a suitable copper area of the printed circuit
board (Figure 11) or to an external heatsink (Fig-
ure 12).
The diagram of Figure 13 shows the maximum dis-
sipable power Ptot and the Rth (j-a) as a function of
the side "I" of two equal square copper areas hav-
ing a thicknessof 35
(1.4 mils).
During soldering the pins temperature must not
exceed 260°C and the soldering time must not be
longer than 12 seconds.
The external heatsink or printed circuit copper
area must be connected to electrical ground.
