... The TISP61089AS is a dual forward-conducting buffered p-gate overvoltage protector designed to protect ringing SLICs (Subscriber Line Interface Circuits) against overvoltages on the telephone line caused by lightning, a.c. power contact and induction. The TISP61089AS limits voltages that exceed the SLIC supply rail voltage. The TISP61089AS parameters are specified to allow equipment compliance with Bellcore GR- 1089-CORE, Issue 1 ...

... SLIC supply during overvoltages caused by power cross and induction. The TISP61089AS is the TISP61089AD with a different pinout. The feed-through Ring (leads 4 — 5) and Tip (leads 1 — 8) connections have been replaced by single Ring (lead 4) and Tip (lead 1) connections. This increases package creepage distance of the biased to ground connections from about 0 ...

... Figures 4. and 5. show how the TISP61089AS limits negative and positive overvoltages. Positive overvoltages (Figure 5) are clipped by the antiparallel diodes in the TISP61089AS and the resulting current is diverted to ground. Negative overvoltages (Figure 4.) are initially clipped close to the SLIC negative supply rail value (V ) ...

... As shown in table 1, the peak currents for these surges are 2x20 A and 2x56 A respectively. The protector must survive the 2x20 A 10/1000 surge and the TISP61089AS will do this as its rating is 2x30 A. When both conductors are surged simultaneously the return (anode) current will again the TISP61089AS will survive this as its rating for this condition will ...

... The 2/10 generator has fictive output resistances of 15 compensates for this by adding an extra resistances of 12 generator. In practice, this extra resistance causes the prospective short-circuit current wave shape to be similar to the 1.2/50 open-circuit voltage wave shape. The TISP61089AS will survive the 2x27 A 1.2/50 as its rating is 2x100 ...

... The most significant tests are a long duration (900 s) medium current test and a higher current tests of 60 one second power applications. As shown in table 4, the peak currents for these tests are 2x0.37 A and 2x1.3 A respectively gate voltage of -80 V, the TISP61089AS will survive both these conditions as its ratings are 2x0.92 A and 2x4.8 A for these time periods A ...

... Using a 25 series resistor will result in table 5. I and 2x2.9. The TISP61089AS will probably fail for a peak current level of 2x24 A and the series current limiting element must operate in under 0. prevent exceeding the TISP61089AS package limit. For 2x7.7 A, the series current limiting element must operate within 0.3 s for TISP61089AS survival. ...

One is the TISP61089AS rated current at gate voltage of -100 V and the other for a gate voltage of -60 V. The overcurrent protector should not allow current-time durations greater than this otherwise the TISP61089AS may fail ...
