dual programmable transient voltage suppressor(tvs) revision march 12, 2014 1 / 3 @ socay electronics co., ltd. 2014 specifications are subject to change without notice. please refer to www.socay.com for current information. S61089, S61089a & S61089b socay electronics co., ltd. www.socay.com sop-8 this device has been especially designed to protect subscriber line card interfaces (slic) against transient over-voltages. positive overloads are clipped with 2 diodes. negative surges are suppressed by 2 thyristors, their breakdown voltage being referenced to-v bat through the gate. this component presents a very low gate triggering current (i gt ) in order to reduce the current consumption on printed circuit board during the firing phase. a particular attention has been given to the internal wire bonding. the configuration ensures reliable protection, eliminating the overvoltage introduced by the parasitic inductances of the wiring (ldi/dt), especially for very fast transients. u dual line programmable transient voltage suppressor u wide negative firing voltage rage : v mgl = -75v (S61089) v mgl = -100v (S61089a) v mgl = -155v (S61089b) u low dynamic switching voltages v fp and v dgl u low gate triggering current: i gt = 5ma max u peak pulse current: i pp = 30a (10/1000 s) u holding current: i h > 150ma the devices are not subject to ageing and provide a fail safe mode in short circuit for a better protection. they are used to help equipment to meet various standards such as ul1950, iec / csa c22.2, ul1459 and fcc part68. type marking S61089 se69 S61089a se69a S61089b se69b parameter symbol value units repetitive peak o ff - state voltage, v gk =0 S61089 v drm - 90 v S61089a - 120 S61089b -170 repetit ive peak gate - cathode voltage, v k a =0 S61089 v gkrm - 85 v S61089a -120 S61089b - 170 non - repetitive peak on - state current i ppsm a 10/1000 s (telcordia (bellcore) gr-1089-core, issue 2, february 1999, section 4) 30 5/320 s (itu-t k.20,k.218 & k.45,k.44 open-circuit voltage wave shape 10/7000 ) 40 1.2/50 s (telcordia (bellcore) gr-1089-core, issue 2, february 1999, section 4) 100 2/10 s (telcordia (bellcore) gr-1089-core, issue 2, february 1999, section 4) 120 non - repetitive peak on - state current. v gg = - 75v 50hz to 60hz 0.1s i tsm 11 a 1s 4.8 5s 2.7 300s 0.95 900s 0.93 operating free - air temperature range t a -40 ~ +85 c operating junction temperature range t j - 40 ~ +150 c storage temperature range t stg - 40 ~ +150 c d escription feature functional diagram benefits marking absolute maximum ratings
