1 1, 2 and 4-Channl ow Capaitan S Prottion rrays Produt sription Th family of diod arrays has bn dsignd to provid S prottion for ltroni omponnts or subsystms rquiring minimal apaitiv loading. Ths dvis ar idal for protting systms with high data and lok rats or for iruits rquiring low apaitiv loading. ah S hannl onsists of a pair of diods in sris whih str th positiv or ngativ S urrnt puls to ithr th positiv (V P ) or ngativ (V N ) supply rail. Znr diod is mbddd btwn V P and V N, offring two advantags. First, it protts th V CC rail against S striks, and sond, it liminats th nd for a bypass apaitor that would othrwis b ndd for absorbing positiv S striks to ground. Th will prott against S pulss up to 8 kv pr th IC standard. Ths dvis ar partiularly wll suitd for protting systms using high spd ports suh as USB 2.0, I1394 (Firwir, iink), Srial T, VI, HMI and orrsponding ports in rmovabl storag, digital amordrs, V RW drivs and othr appliations whr xtrmly low loading apaitan with S prottion ar rquird in a small pakag footprint.

7 PPICTION INFORMTION sign Considrations In ordr to raliz th maximum prottion against S pulss, ar must b takn in th PCB layout to minimiz parasiti sris indutans on th Supply/Ground rails as wll as th signal tra sgmnt btwn th signal input (typially a onntor) and th S prottion dvi. Rfr to ppliation of Positiv S Puls btwn Input Channl and Ground, whih illustrats an xampl of a positiv S puls striking an input hannl. Th parasiti sris indutan bak to th powr supply is rprsntd by 1 and 2. Th voltag V C on th lin bing prottd is: V C = Fwd Voltag rop of 1 + V SUPPY + 1 x d(i S ) / dt + 2 x d(i S ) / dt whr I S is th S urrnt puls, and V SUPPY is th positiv supply voltag. n S urrnt puls an ris from zro to its pak valu in a vry short tim. s an xampl, a lvl 4 ontat disharg pr th IC standard rsults in a urrnt puls that riss from zro to 30 mps in 1 ns. Hr d(i S )/dt an b approximatd by I S /t, or 30/(1x10 9 ). So just 10 nh of sris indutan ( 1 and 2 ombind) will lad to a 300 V inrmnt in V C! Similarly for ngativ S pulss, parasiti sris indutan from th V N pin to th ground rail will lad to drastially inrasd ngativ voltag on th lin bing prottd. Th has an intgratd Znr diod btwn V P and V N. This gratly rdus th fft of supply rail indutan 2 on V C by lamping V P at th brakdown voltag of th Znr diod. Howvr, for th lowst possibl V C, spially whn V P is biasd at a voltag signifiantly blow th Znr brakdown voltag, it is rommndd that a 0.22 F rami hip apaitor b onntd btwn V P and th ground plan. s a gnral rul, th S Prottion rray should b loatd as los as possibl to th point of ntry of xptd ltrostati dishargs. Th powr supply bypass apaitor mntiond abov should b as los to th V P pin of th Prottion rray as possibl, with minimum PCB tra lngths to th powr supply, ground plans and btwn th signal input and th S dvi to minimiz stray sris indutan. dditional Information S also ON Smiondutor ppliation Not sign Considrations for S Prottion, in th ppliations stion.
