description
These medium voltage symmetrical transient
voltage suppressor devices are designed to
protect two wire telecommunication applications
against transients caused by lightning strikes
and a.c. power lines. Offered in three 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
level, which causes the device to crowbar. The
PRODUCT
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.

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 (Zθ ).
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 µs wave shape would have a peak current value of
50 A, a rise time of 5 µs and a decay time of 310 µs. 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 µs 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 µs open circuit voltage and 8/20 µs 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 µs open circuit voltage generator typically produces a 5/310 µs 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 µs surge is
changed to a 38 A, 5/310 µs 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 µs
on the surge graph and not 700 µs. Some common short circuit equivalents are tabulated below:

50 A, 5/200 µs
50 A, 5/310 µs
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 Ω (2000/50). If the equipment has a series resistance of 25 Ω then the
surge current requirement of the TISP becomes 31 A (2000/65) and not 50 A.

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 µs surge has an average dv/dt of 150 V/µs, but, as the rise
is exponential, the initial dv/dt is higher, being in the region of 450 V/µs. The instantaneous generator output
resistance is 25 Ω. If the equipment has an additional series resistance of 20 Ω, the total series resistance
becomes 45 Ω. The maximum di/dt then can be estimated as 450/45 = 10 A/µs. 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 25°C 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.
