november 2001 - revised february 2005 specifications are subject to change without notice. customers should verify actual device performance in their specific applications. applications information tisp43xxmmaj/bj overvoltage protector series fcc part 68, acta, tia and eia fuse values for tia/eia-is-968 (fcc part 68) fuses must not operate on the type b surge. to survive a 37.5 a type b surge, the fuse needs to have a melting i 2 t of greater than 0.7 a 2 s. to survive the type a surges a fuse melting i 2 t value of greater than 10 a 2 s for 10/160 and 8 a 2 s for 10/560 is needed. by using a fuse which does not operate on type b surges (i 2 t > 0.7 a 2 s) and does operate on type a surges (i 2 t < 8 a 2 s) a non-operational pass can be achieved for t ype a testing. from 2001, the registrations for fcc equipment changed from the fcc to acta, administrative council for terminal attachments. f or this function, acta needed to adopt a us national standard specifying terminal equipment requirements. the tia, telecommunications industry association, in conjunction with the eia, electronic industries alliance, created tia/eia-is-968 for this purpose. the first issue of tia/eia-is-968 is essentially a renumbered version of the fcc part 68 requirement. clause and figure changes are shown in the t able. item fcc part 68 tia/eia-is-968 te lephone line surge ?type a clause 68.302 (b) clause 4.2.2 te lephone line surge ?type b clause 68.302 (c) clause 4.2.3 si mplified surge generator fig. 68.302 (a) figure 4.1 op en circuit voltage wave shape fig. 68.302 (b) figure 4.2 sh ort circuit current wave shape fig. 68.302 (c) figure 4.3 tia/eia-is-968 (fcc part 68) impulse testing to verify the withstand capability and safety of the equipment, standards require that the equipment is tested with various imp ulse wave forms. the table below shows values for the tia/eia-is-968 and itu-t recommendation k.21. standard te s t condition v peak vol tage v vol ta ge wave form s peak current a current wave form s fictive impedance ? tisp43xxmm rating a series resistance ? tia/eia-is-968 (f cc part 68) longitudinal 1500 10/160 200 10/160 7.5 75 2 x 13 metallic 800 10/560 100 10/560 8 55 7 longitudinal 1500 9/720 ? 37.5 5/320 ? 40 65 0 metallic 1000 9/720 ? 25 5/320 ? 40 65 0 itu-t k.21 basic level t ransverse 1500 4000 10/700 37.5 100 5/310 40 65 0 6.6 itu-t k.21 enhanced level t ransverse 1500 6000 10/700 37.5 125 5/310 40 65 0 6.2 ? tia/eia-is-968 terminology for the wave forms produced by the itu-t recommendation k.21 10/700 impulse generator ? v alues assume the tisp43xxmm is connected inter-conductor and a 400 v primary is used if the impulse generator current exceeds the protectors current rating then a series resistance can be used to reduce the curr ent to the protectors rated value to prevent possible failure. for the new edition of itu-t recommendation k.21 (2000) some series resist ance might be needed to pass the impulse coordination test. the value for a 400 v primary protector is given in the table. the required value of device survival series resistance for a given waveform is given by the following calculations. first, the minimum total circuit impedance is found by dividing the impulse generators peak voltage by the protectors rated current. the impulse gener ators fictive impedance (generators peak voltage divided by peak short circuit current) is then subtracted from the minimum total circuit im pedance to give the required value of series resistance. for the tia/eia-is-968 10/560 waveform the following values result. the minimum total circuit impedance is 800/55 = 15 ? and the generators fictive impedance is 800/100 = 8 ? . for an inter-conductor connected tisp43xxmm, this gives a minimum series resistance value of 15 - 8 = 7 ? . the 10/160 waveform only needs to be considered if the tisp43xxmm is connected from the conductor to ground. in this case the conductor series resistance is 12.5 ? per conductor.
