Device Symbol

These devices are designed to limit overvoltages on the telephone and data lines. Overvoltages are normally caused by a.c. power system or

lightning flash disturbances which are induced or conducted on to the telephone line. A single device provides 2-point protection and is

typically used for the protection of ISDN power supply feeds. Two devices, one for the Ring output and the other for the Tip output, will provide

protection for single supply analogue SLICs. A combination of three devices will give a low capacitance protector network for the 3-point

protection of ISDN lines.

The protector consists of a voltage-triggered unidirectional thyristor with an anti-parallel diode. Negative 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

prevents d.c. latchup as the diverted current subsides. Positive overvoltages are limited by the conduction of the anti-parallel diode.

APPLICATIONS INFORMATION

These devices are two terminal overvoltage protectors. They may be used either singly to limit the voltage between two points (Figure 11) or in

multiples to limit the voltage at several points in a circuit (Figure 12).

In Figure 11, the TISP5xxxH3BJ limits the maximum voltage of the negative supply to -V(BO) and +VF. This configuration can be used for

protecting circuits where the voltage polarity does not reverse in normal operation. In Figure 12, the two TISP5xxxH3BJ protectors, Th4 and

Th5, limit the maximum voltage of the SLIC (Subscriber Line Interface Circuit) outputs to -V(BO) and +VF. Ring and test protection is given by

protectors Th1, Th2 and Th3. Protectors Th1 and Th2 limit the maximum tip and ring wire voltages to the ±V(BO) of the individual protector.

Protector Th3 limits the maximum voltage between the two conductors to its ±V(BO) value. If the equipment being protected has all its

vulnerable components connected between the conductors and ground, then protector Th3 is not required.

The star-connection of three TISP5xxxH3BJ protectors gives a protection circuit which has a low differential capacitance to ground (Figure 13).

This example, a -100 V ISDN line is protected. In Figure 13, the circuit illustration A shows that protector Th1 will be forward biased as it is

connected to the most negative potential. The other two protectors, Th2 and Th3 will be reverse biased as protector Th1 will pull their common

connection to within 0.5 V of the negative voltage supply.

Illustration B shows the equivalent capacitances of the two reverse biased protectors (Th2 and Th3) as 29 pF each and the capacitance of the

forward biased protector (Th1) as 600 pF. Illustration C shows the delta equivalent of the star capacitances of illustration B. The protector

circuit differential capacitance will be 26 - 1 = 25 pF. In this circuit, the differential capacitance value cannot exceed the capacitance value of

the ground protector (Th3).

A bridge circuit can be used for low capacitance differential. Whatever the potential of the ring and tip conductors are in Figure 14, the array of

steering diodes, D1 through to D6, ensure that terminal 1 of protector Th1 is always positive with respect to terminal 2. The protection voltage

will be the sum of the protector Th1, V(BO), and the forward voltage of the appropriate series diodes. It is important to select the correct

diodes. Diodes D3 through to D6 divert the currents from the ring and tip lines. Diodes D1 and D2 will carry the sum of the ring and tip currents

and so conduct twice the current of the other four diodes. The diodes need to be specified for forward recovery voltage, VFRM, under the

expected impulse conditions. (Some conventional a.c. rectifiers can produce as much as 70 V of forward recovery voltage, which would be an

extra 140 V added to the V(BO) of Th1). In principle the bridge circuit can be extended to protect more than two conductors by adding extra

legs to the bridge.

ISDN Device Selection

The ETSI Technical Report ETR 080:1993 defines several range values in terms of maximum and minimum ISDN feeding voltages. The

following table shows that ranges 1 and 2 can use a TISP5110H3BJ protector and ranges 3 to 5 can use a TISP5150H3BJ protector.

Impulse Testing

To verify the withstand capability and safety of the equipment, standards require that the equipment is tested with various impulse wave forms.

The table below shows some common values.

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 and so 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 rated waveform values from Figure 10, the appropriate series resistor value can be calculated for ambient

temperatures in the range of -40 °C to 85 °C.

If the devices are used in a star-connection, then the ground return protector, Th3 in Figure 13, will conduct the combined current of protectors

Th1 and Th2. Similarly in the bridge connection (Figure 14), the protector Th1 must be rated for the sum of the conductor currents. In these

cases, it may be necessary to include some series resistance in the conductor feed to reduce the impulse current to within the protector’s

ratings.

JANUARY 1998 - REVISED JUNE 2004

The protector characteristic off-state capacitance values are given for d.c. bias voltage, VD, values of -1 V, -2 V and -50 V. The TISP5150H3BJ

and TISP5190H3BJ are also given for a bias of -100 V. Values for other voltages may be determined from Figure 6. Up to 10 MHz, the

capacitance is essentially independent of frequency. Above 10 MHz, the effective capacitance is strongly dependent on connection inductance.

In Figure 12, the typical conductor bias voltages will be about -2 V and -50 V. Figure 7 shows the differential (line unbalance) capacitance

caused by biasing one protector at -2 V and the other at -50 V. For example, the TISP5070H3BJ has a differential capacitance value of 166 pF

under these conditions.

The protector should not clip or limit the voltages that occur in normal system operation. Figure 9 allows the calculation of the protector VDRM

value at temperatures below 25 °C. The calculated value should not be less than the maximum normal system voltages. The TISP5150H3BJ,

with a VDRM of -120 V, can be used to protect ISDN feed voltages having maximum values of -99 V, -110 V and -115 V (range 3 through to

range 5). These three range voltages represent 0.83 (99/120), 0.92 (110/120) and 0.96 (115/120) of the -120 V TISP5150H3BJ VDRM. Figure 9

shows that the VDRM will have decreased to 0.944 of its 25 °C value at -40 °C. Thus, the supply feed voltages of -99 V (0.83) and -110 V (0.92)

will not be clipped at temperatures down to -40 °C. The -115 V (0.96) feed supply may be clipped if the ambient temperature falls below -21 °C.

Normal System Voltage Levels

JESD51 Thermal Measurement Method

To standardize thermal measurements, the EIA (Electronic Industries Alliance) has created the JESD51 standard. Part 2 of the standard

(JESD51-2, 1995) describes the test environment. This is a 0.0283 m3 (1 ft3 ) cube which contains the test PCB (Printed Circuit Board)

horizontally mounted at the center. Part 3 of the standard (JESD51-3, 1996) defines two test PCBs for surface mount components; one for

packages smaller than 27 mm on a side and the other for packages up to 48 mm. The SMB (DO-214AA) measurements used the smaller 76.2

mm x 114.3 mm (3.0 ” x 4.5 ”) PCB. The JESD51-3 PCBs are designed to have low effective thermal conductivity (high thermal resistance) and

represent a worse case condition. The PCBs used in the majority of applications will achieve lower values of thermal resistance and so can

dissipate higher power levels than indicated by the JESD51 values.

TISP5xxxH3BJ Overvoltage Protection Series

APPLICATIONS INFORMATION

The protector can withstand currents applied for times not exceeding those shown in Figure 8. Currents that exceed these times must be

terminated or reduced to avoid protector failure. Fuses, PTC (Positive Temperature Coefficient) resistors and fusible resistors are overcurrent

protection devices which can be used to reduce the current flow. Protective fuses may range from a few hundred milliamperes to one ampere.

In some cases it may be necessary to add some extra series resistance to prevent the fuse opening during impulse testing. The current versus

time characteristic of the overcurrent protector must be below the line shown in Figure 8. In some cases there may be a further time limit

imposed by the test standard (e.g. UL 1459 wiring simulator failure).
