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 external heatsink (fig. 13). the diagram of figure 14 shows the maximum dis- sipable power p tot and the r th j-amb as a function of the side " " of two equal square copper areas hav- ing a thickness of 35 m (1.4 mils). during soldering the pins temperature must not ex- ceed 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. figure 12 : example of p.c. board area which is used as heatsink. figure 13 : external heatsink mounting example. figure 14 : maximum dissipable power and junc- tion to ambient thermal resistance vs. side "i". figure 15 : maximum allowable power dissipa- tion vs. ambient temperature. uln2065b-uln2067b-ULN2069B-uln2071b-uln2075b-uln2077b 5/7
