AN807 Mounting LITTLE FOOT SOT-3 Powr MOSFETs Wharton McDanil Surfac-mountd LITTLE FOOT powr MOSFETs us intgratd circuit and small-signal packags which hav bn bn modifid to provid th hat transfr capabilitis rquird by powr dvics. Ladfram matrials and dsign, molding compounds, and di attach matrials hav bn changd, whil th footprint of th packags rmains th sam. ambint air. This pattrn uss all th availabl ara undrnath th body for this purpos. 0.4.9 S Application Not 86, Rcommndd Minimum Pad Pattrns With Outlin Drawing Accss for MOSFETs, (http:///doc?786), for th basis of th pad dsign for a LITTLE FOOT SOT-3 powr MOSFET footprint. In convrting this footprint to th pad st for a powr dvic, dsignrs must mak two connctions: an lctrical connction and a thrmal connction, to draw hat away from th packag. 0.059.5 0.0394.0 0.037 0.95 0.08.05 0.50 3.8 FIGURE. Footprint With Coppr Sprading Th lctrical connctions for th SOT-3 ar vry simpl. Pin is th gat, pin is th sourc, and pin 3 is th drain. As in th othr LITTLE FOOT packags, th drain pin srvs th additional function of providing th thrmal connction from th packag to th PC board. Th total cross sction of a coppr trac connctd to th drain may b adquat to carry th currnt rquird for th application, but it may b inadquat thrmally. Also, hat sprads in a circular fashion from th hat sourc. In this cas th drain pin is th hat sourc whn looking at hat sprad on th PC board. Sinc surfac-mountd packags ar small, and rflow soldring is th most common way in which ths ar affixd to th PC board, thrmal connctions from th planar coppr to th pads hav not bn usd. Evn if additional planar coppr ara is usd, thr should b no problms in th soldring procss. Th actual soldr connctions ar dfind by th soldr mask opnings. By combining th basic footprint with th coppr plan on th drain pins, th soldr mask gnration occurs automatically. Figur shows th footprint with coppr sprading for th SOT-3 packag. This pattrn shows th starting point for utilizing th board ara availabl for th hat sprading coppr. To crat this pattrn, a plan of coppr ovrlis th drain pin and provids planar coppr to draw hat from th drain lad and start th procss of sprading th hat so it can b dissipatd into th A final itm to kp in mind is th width of th powr tracs. Th absolut minimum powr trac width must b dtrmind by th amount of currnt it has to carry. For thrmal rasons, this minimum width should b at last 0.00 inchs. Th us of wid tracs connctd to th drain plan provids a low-impdanc path for hat to mov away from th dvic. Documnt Numbr: 70739 6-Nov-03
