Description
D Package (Top View)
The TISP7xxxF3 series are 3-point overvoltage protectors designed for protecting against metallic (differential mode) and simultaneous
longitudinal (common mode) surges. Each terminal pair has the same voltage limiting values and surge current capability. This terminal pair
surge capability ensures that the protector can meet the simultaneous longitudinal surge require-ment which is typically twice the metallic surge
requirement.

Description (continued)
TISP7xxxF3 (MV, HV) Overvoltage Protector Series
Absolute Maximum Ratings, TA = 25 °C (Unless Otherwise Noted)
Each terminal pair has a symmetrical voltage-triggered thyristor characteristic. Overvoltages are initially clipped by breakdown clamping until
the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. This low-voltage on state causes the
current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current helps prevent d.c. latchup as
the diverted current subsides.These protectors are guaranteed to voltage limit and withstand the listed lightning surges in both polarities.
These medium and high voltage devices are offered in nine voltage variants to meet a range of battery and ringing voltage requirements. They
are guaranteed to suppress and withstand the listed international lightning surges on any terminal pair. Similar devices with working voltages of
58 V and 66 V are detailed in the TISP7072F3, TISP7082F3 data sheet.

3. Above 70 °C, derate ITSM linearly to zero at 150 °C lead temperature.
Initially, the TISP device must be in thermal equilibrium at the specified T . The impulse may be repeated after the TISP device
returns to its initial conditions. The rated current values may be applied either to the R to G or to the T to G or to the T to R
terminals. Additionally, both R to G and T to G may have their rated current values applied simultaneously (In this case the total
G terminal current will be twice the above rated current values).

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 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 open circuit voltage and 8/20 short circuit current). Circuit specified generators usually equate to a combination generator,
although typically only the open circuit voltage wave shape is referenced (e.g. a 10/700 open circuit voltage generator typically produces a 5/
310 short circuit current). If the combination or circuit defined generators operate into a finite resistance, the wave shape produced is interme-
diate between the open circuit and short circuit values.
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 rise time in microseconds and a decay time in microseconds to 50 % of the maximum
amplitude. The notation used for the wave shape is
rise time/decay time
, without the microseconds quantity and the “/” between the two values
has no mathematical significance. A 50 A, 5/310 waveform 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.

TISP7xxxF3 (MV, HV) Overvoltage Protector Series
These devices are three terminal overvoltage protectors. They limit the voltage between three points in the circuit. Typically, this would be the
two line conductors and protective ground (Figure 32).
In Figure 32, protective functions Th2 and Th3 limit the maximum voltage between each conductor and ground to their respective ±V(BO)
values. Protective function Th1 limits the maximum voltage between the two conductors to its ±V(BO) value.
This circuit defined generator is specified in many standards. The descriptions and values are not consistent between standards and it is
important to realize that it is always the same generator being used.
Figure 33 shows the 10/700 generator circuit defined in ITU-T recommendation K.20 (10/96) “Resistibility of telecommunication switching
equipment to overvoltages and overcurrents”. The basic generator comprises of:
Capacitor C1, charged to voltage VC, which is the energy storage element
Switch SW to discharge the capacitor into the output shaping network
Shunt resistor R1, series resistor R2 and shunt capacitor C2 form the output shaping network
Series feed resistor R3 to connect to one line conductor for single surge
Series feed resistor R4 to connect to the other line conductor for dual surging
In the normal single surge equipment test configuration, the unsurged line is grounded. This is shown by the dotted lines in the top drawing of
Figure 33. However, doing this at device test places one terminal pair in parallel with another terminal pair. To check the individual terminal
pairs of the TISP7xxxF3, without any paralleled operation, the unsurged terminal is left unconnected.

APPLICATIONS INFORMATION
ITU-T 10/700 Generator (continued)
Lightning Surge (continued)
TISP7xxxF3 (MV, HV) Overvoltage Protector Series
With the generator output open circuit, when SW closes, C1 discharges through R1. The decay time constant will be C1R1, or 20 x 50 =
1000 μs. For the 50 % voltage decay time, the time constant needs to be multiplied by 0.697, giving 0.697 x 1000 = 697 μs which is rounded to
700 μs.
The output rise time is controlled by the time constant of R2 and C2, which is 15 x 200 = 3000 ns or 3 μs. Virtual voltage rise times are given
by straight line extrapolation through the 30 % and 90 % points of the voltage waveform to zero and 100 %. Mathematically, this is equivalent to
3.24 times the time constant, which gives 3.24 x 3 = 9.73 which is rounded to 10 μs. Thus, the open circuit voltage rises in 10 μs and decays in
700 μs, giving the 10/700 generator its name.
When the overvoltage protector switches, it effectively shorts the generator output via the series 25 Ω resistor. Two short circuit conditions
need to be considered: single output using R3 only (top circuit of Figure 33) and dual output using R3 and R4 (bottom circuit of Figure 33).
For the single test, the series combination of R2 and R3 (15 + 25 = 40 Ω) is in shunt with R1. This lowers the discharge resistance from 50 Ω to
22.2 Ω, giving a discharge time constant of 444 μs and a 50% current decay time of 309.7 μs, which is rounded to 310 μs.
For the rise time, R2 and R3 are in parallel, reducing the effective source resistance from 15 Ω to 9.38 Ω, giving a time constant of 1.88 μs.
Virtual current rise times are given by straight line extrapolation through the 10 % and 90 % points of the current waveform to zero and 100 %.
Mathematically, this is equivalent to 2.75 times the time constant, which gives 2.75 x 1.88 = 5.15, which is rounded to 5 μs. Thus, the short
circuit current rises in 5 μs and decays in 310 μs, giving the 5/310 wave shape.
The series resistance from C1 to the output is 40 Ω, giving an output conductance of 25 A/kV. For each 1 kV of capacitor charge voltage, 25 A
of output current will result.
For the dual test, the series combination of R2 plus R3 and R4 in parallel (15 + 12.5 = 27.5 Ω) is in shunt with R1. This lowers the discharge
resistance from 50 Ω to 17.7 Ω, giving a discharge time constant of 355 μs and a 50% current decay time of 247 μs, which is rounded to
250 μs.
For the rise time, R2, R3 and R4 are in parallel, reducing the effective source resistance from 15 Ω to 6.82 Ω, giving a time constant of 1.36 μs,
which gives a current rise time of 2.75 x 1.36 = 3.75, which is rounded to 4 μs. Thus, the short circuit current rises in 4 μs and decays in 250
μs, giving the 4/250 wave shape.

TISP7xxxF3 (MV, HV) Overvoltage Protector Series
The series resistance from C1 to an
individual
output is 2 x 27.5 = 55 Ω, giving an output conductance of 18 A/kV. For each 1 kV of capacitor
charge voltage, 18 A of output current will result.
At 25 °C, these protectors are rated at 70 A for the single terminal pair condition and 95 A for the dual condition (R and G terminals and T and
G terminals). In terms of generator voltage, this gives a maximum generator setting of 70 x 40 = 2.8 kV for the single condition and 2 x 95 x
27.5 = 5.2 kV for the dual condition. The higher generator voltage setting for the dual condition is due to the current waveform decay being
shorter at 250 μs compared to the 310 μs value of the single condition.
Other ITU-T recommendations use the 10/700 generator: K.17 (11/88) “Tests on power-fed repeaters using solid-state devices in order to
check the arrangements for protection from external interference” and K.21(10/96) “Resistibility of subscriber’s terminal to overvoltages and
overcurrents”, K.30 (03/93) “Positive temperature coefficient (PTC) thermistors”.
Several IEC publications use the 10/700 generator; common ones are IEC 6100-4-5 (03/95) “Electromagnetic compatibility (EMC) - Part 4:
Testing and measurement techniques - Section 5: Surge immunity test” and IEC 60950 (04/ 99) “Safety of information technology equipment”.
The IEC 60950 10/700 generator is carried through into other “950” derivatives. Europe is harmonized by CENELEC (Comité Européen de
Normalization Electro-technique) under EN 60950 (included in the Low Voltage Directive, CE mark). US has UL (Underwriters Laboratories)
1950 and Canada CSA (Canadian Standards Authority) C22.2 No. 950.
FCC Part 68 “Connection of terminal equipment to the telephone network” (47 CFR 68) uses the 10/700 generator for Type B surge testing.
Part 68 defines the open circuit voltage wave shape as 9/720 and the short circuit current wave shape as 5/320 for a single output. The current
wave shape in the dual (longitudinal) test condition is not defined, but it can be assumed to be 4/250.
Several VDE publications use the 10/700 generator, for example: VDE 0878 Part 200 (12/92) ”Electromagnetic compatibility of information
technology equipment and telecommunications equipment; Immunity of analogue subscriber equipment”.
The 1.2/50 open circuit voltage and 8/20 short circuit current combination generator is defined in IEC 61000-4-5 (03/95) “Electromagnetic
compatibility (EMC) - Part 4: Testing and measurement techniques - Section 5: Surge immunity test”. This generator has a fictive output
resistance of 2 Ω, meaning that dividing the open circuit output voltage by the short circuit output current gives a value of 2 Ω(500 A/kV).
The combination generator has three testing configurations; directly applied for testing between equipment a.c. supply connections, applied
via an external 10 Ω resistor for testing between the a.c. supply connections and ground, and applied via an external 40 Ω resistor for testing
all other lines. For unshielded unsymmetrical data or signalling lines, the combination generator is applied via a 40 Ω resistor either between
lines or line to ground. For unshielded symmetrical telecommunication lines, the combination generator is applied to all lines via a resistor of
n x 40 Ω, where n is the number of conductors and the maximum value of external feed resistance is 250 Ω. Thus, for four conductors, n = 4
and the series resistance is 4 x 40 = 160 Ω. For ten conductors, the resistance cannot be 10 x 40 = 400 Ω and must be 250 Ω. The combina-
tion generator is used for short distance lines; long distance lines are tested with the 10/700 generator.
When the combination generator is used with a 40 Ω, or more, external resistor, the current wave shape is not 8/20, but becomes closer to the
open circuit voltage wave shape of 1.2/50. For example, a commercial generator when used with 40 Ω produced an 1.4/50 wave shape.
The wave shapes of 1.2/50 and 8/20 occur in other generators as well. British Telecommunication has a combination generator with 1.2/50
voltage and 8/20 current wave shapes, but it has a fictive resistance of 1 Ω. ITU-T recommendation K.22 “Overvoltage resistibility of equip-
ment connected to an ISDN T/S BUS” (05/95) has a 1.2/50 generator option using only resistive and capacitive elements, Figure 34.
The K.22 generator produces a 1.4/53 open circuit voltage wave. Using 25 Ω output resistors, gives a single short circuit current output wave
shape of 0.8/18 with 26 A/kV and a dual of 0.6/13 with 20 A/kV. These current wave shapes are often rounded to 1/20 and 0.8/14.

Impulse Testing
TISP7xxxF3 (MV, HV) Overvoltage Protector Series
There are 8/20 short circuit current defined generators. These are usually very high current, 10 kA or more and are used for testing a.c.
protectors, primary protection modules and some Gas Discharge Tubes.
To verify the withstand capability and safety of the equipment, standards require that the equipment is tested with various impulse wave forms.
The table in this section shows some common test values.
Manufacturers are being increasingly required to design in protection coordination. This means that each protector is operated at its design
level and currents are diverted through the appropriate protector, e.g. the primary level current through the primary protector and lower levels
of current may be diverted through the secondary or inherent equipment protection. Without coordination, primary level currents could pass
through the equipment only designed to pass secondary level currents. To ensure coordination happens with fixed voltage protectors, some
resistance is normally used between the primary and secondary protection (R1a and R1b, Figure 36). The values given in this data sheet apply
to a 400 V (d.c. sparkover) gas discharge tube primary protector and the appropriate test voltage when the equipment is tested with a primary
protector.
If the impulse generator current exceeds the protector’s current rating, then a series resistance can be used to reduce the current to the
protector’s rated value to prevent possible failure. The required value of series resistance for a given waveform is given by the following
calculations. First, the minimum total circuit impedance is found by dividing the impulse generator’s peak voltage by the protector’s rated
current. The impulse generator’s fictive impedance (generator’s peak voltage divided by peak short circuit current) is then subtracted from the
minimum total circuit impedance to give the required value of series resistance. In some cases, the equipment will require verification over a
temperature range. By using the derated waveform values from the thermal information section, the appropriate series resistor value can be
calculated for ambient temperatures in the range of 0 °C to 70 °C.
