Offered in five voltage variants to meet battery and protection requirements they are guaranteed to suppress and withstand the listed international lightning surges in both polarities. Transients are initially clipped by breakdown clamping until the voltage rises to the breakover PRODUCT 6 R level, which causes the device to crowbar. The high crowbar holding current prevents d.c. latchup as the current subsides. These monolithic protection devices are fabricated in ion-implanted planar structures to ensure precise and matched breakover control and are virtually transparent to the system in normal operation The small-outline 8-pin assignment has been carefully chosen for the TISP series to maximise the inter-pin clearance and creepage distances which are used by standards (e.g. IEC950) to establish voltage withstand ratings.

INFORMATION 7 TISP4240F3, TISP4260F3, TISP4290F3, TISP4320F3, TISP4380F3 SYMMETRICAL TRANSIENT VOLTAGE SUPPRESSORS MARCH 1994 - REVISED SEPTEMBER 1997 APPLICATIONS INFORMATION electrical characteristics The electrical characteristics of a TISP are strongly dependent on junction temperature, TJ. Hence a characteristic value will depend on the junction temperature at the instant of measurement. The values given in this data sheet were measured on commercial testers, which generally minimise the temperature rise caused by testing. Application values may be calculated from the parameters' temperature curves, the power dissipated and the thermal response curve (Z ). lightning surge wave shape notation Most lightning tests, used for equipment verification, specify a unidirectional sawtooth waveform which has an exponential rise and an exponential decay. Wave shapes are classified in terms of peak amplitude (voltage or current), rise time and a decay time to 50% of the maximum amplitude. The notation used for the wave shape is amplitude, rise time/decay time. A 50A, 5/310 s wave shape would have a peak current value of 50 A, a rise time of 5 s and a decay time of 310 s. The TISP surge current graph comprehends the wave shapes of commonly used surges. generators There are three categories of surge generator type, single wave shape, combination wave shape and circuit defined. Single wave shape generators have essentially the same wave shape for the open circuit voltage and short circuit current (e.g. 10/1000 s open circuit voltage and short circuit current). Combination generators have two wave shapes, one for the open circuit voltage and the other for the short circuit current (e.g. 1.2/50 s open circuit voltage and 8/20 s short circuit current) Circuit specified generators usually equate to a combination generator, although typically only the open circuit voltage waveshape is referenced (e.g. a 10/700 s open circuit voltage generator typically produces a 5/310 s short circuit current). If the combination or circuit defined generators operate into a finite resistance the wave shape produced is intermediate between the open circuit and short circuit values. current rating When the TISP switches into the on-state it has a very low impedance. As a result, although the surge wave shape may be defined in terms of open circuit voltage, it is the current wave shape that must be used to assess the required TISP surge capability. As an example, the CCITT IX K17 1.5 kV, 10/700 s surge is changed to a 38 A, 5/310 s waveshape when driving into a short circuit. Thus the TISP surge current capability, when directly connected to the generator, will be found for the CCITT IX K17 waveform at 310 s on the surge graph and not 700 s. Some common short circuit equivalents are tabulated below: STANDARD OPEN CIRCUIT VOLTAGE SHORT CIRCUIT CURRENT CCITT IX K17 CCITT IX K20 RLM88 VDE 0433 FTZ R12 1.5 kV, 10/700 s 1 kV, 10/700 s 1.5 kV, 0.5/700 s 2.0 kV, 10/700 s 2.0 kV, 10/700 s 38 A, 5/310 s 25 A, 5/310 s 38 A, 0.2/310 s 50 A, 5/200 s 50 A, 5/310 s Any series resistance in the protected equipment will reduce the peak circuit current to less than the generators' short circuit value. A 2 kV open circuit voltage, 50 A short circuit current generator has an effective output impedance of 40 (2000/50). If the equipment has a series resistance of 25 then the surge current requirement of the TISP becomes 31 A (2000/65) and not 50 A. PRODUCT 8 INFORMATION TISP4240F3, TISP4260F3, TISP4290F3, TISP4320F3, TISP4380F3 SYMMETRICAL TRANSIENT VOLTAGE SUPPRESSORS MARCH 1994 - REVISED SEPTEMBER 1997 APPLICATIONS INFORMATION protection voltage The protection voltage, (V(BO) ), increases under lightning surge conditions due to thyristor regeneration. This increase is dependent on the rate of current rise, di/dt, when the TISP is clamping the voltage in its breakdown region. The V(BO) value under surge conditions can be estimated by multiplying the 50 Hz rate V(BO) (250 V/ms) value by the normalised increase at the surge's di/dt (Figure 7.) . An estimate of the di/dt can be made from the surge generator voltage rate of rise, dv/dt, and the circuit resistance. As an example, the CCITT IX K17 1.5 kV, 10/700 s surge has an average dv/dt of 150 V/s, but, as the rise is exponential, the initial dv/dt is higher, being in the region of 450 V/s. The instantaneous generator output resistance is 25 . If the equipment has an additional series resistance of 20 , the total series resistance becomes 45 . The maximum di/dt then can be estimated as 450/45 = 10 A/s. In practice the measured di/dt and protection voltage increase will be lower due to inductive effects and the finite slope resistance of the TISP breakdown region. capacitance off-state capacitance The off-state capacitance of a TISP is sensitive to junction temperature, TJ , and the bias voltage, comprising of the dc voltage, VD , and the ac voltage, Vd . All the capacitance values in this data sheet are measured with an ac voltage of 100 mV. The typical 25C variation of capacitance value with ac bias is shown in Figure 13 When VD >> Vd the capacitance value is independent on the value of Vd . The capacitance is essentially constant over the range of normal telecommunication frequencies.
