MOUNTING INSTRUCTIONS

The R_{th j-amb}can be reduced by soldering the GND

pins to a suitable copper area of the printed circuit

board(Fig. 12) or to an externalheatsink(Fig. 13).

During soldering the pins temperature must not ex-

ceed 260 °C and the soldering time must not be

longerthan 12 seconds.

The diagram of Figure 14 shows the maximum dis-

sipable power P_totand the R_{th j-amb}as a function of

the side ”α” of two equalsquare copper areashav-

ing a thickness of 35 µ (1.4mils).

The externalheatsinkor printedcircuit copper area

must be connectedto electrical ground.
