BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS
TISP4xxxM3BJ Overview
This TISP® device series protects central office, access and customer premise equipment against overvoltages on the telecom line. The
TISP4xxxM3BJ is available in a wide range of voltages and has a medium current capability. These protectors have been specified mindful of
the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T K.20, K.21 and K.45. The
TISP4350M3BJ meets the FCC Part 68 “B” ringer voltage requirement (VDRM = ±275 V) and survives the Type B impulse tests. For FCC Part
68 ADSL applications, the TISP4360H3BJ is recommended. The TISP4360H3BJ has an extra 15 V in working level (VDRM = ±290 V) to avoid
clipping the ADSL signal during ringing peaks. The TISP4xxxM3BJ series is housed in a surface mount SMB (DO-214AA) package.

Description
These devices are designed to limit overvoltages on the telephone line. 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 2-wire telecommunication equipment (e.g. between the Ring and Tip wires for telephones and modems). Combinations of
devices can be used for multi-point protection (e.g. 3-point protection between Ring, Tip and Ground).
The protector consists of a symmetrical voltage-triggered bidirectional thyristor. 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.

TISP4xxxM3BJ Overvoltage Protector Series
These devices are two terminal overvoltage protectors. They may be used either singly to limit the voltage between two conductors (Figure 13)
or in multiples to limit the voltage at several points in a circuit (Figure 14).
APPLICATIONS INFORMATION
Deployment
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.
Figure 13. Two Point Protection
Th1
Figure 14. Multi-Point Protection
Th3
Th2
Th1
In Figure 13, protector Th1 limits the maximum voltage between the two conductors to ±V(BO). This configuration is normally used to protect
circuits without a ground reference, such as modems. In Figure 14, protectors Th2 and Th3 limit the maximum voltage between each conduc-
tor and ground to the ±V(BO) of the individual protector. Protector Th1 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 Th1
is not required.

† FCC Part 68 terminology for the waveforms produced by the ITU-T recommendation K.21 10/700 impulse generator
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.
For the FCC Part 68 10/560 waveform, the following values result. The minimum total circuit impedance is 800/75 = 10.7 Ω and the generator’s
fictive impedance is 800/100 = 8 Ω. This gives a minimum series resistance value of 10.7 - 8 = 2.7 Ω. After allowing for tolerance, a 3 Ω ±10%
resistor would be suitable. The 10/160 waveform needs a standard resistor value of 5.6 Ω per conductor. These would be R1a and R1b in
Figure 16 and Figure 17. FCC Part 68 allows the equipment to be non-operational after the 10/160 (conductor to ground) and 10/560 (inter-
conductor) impulses. The series resistor value may be reduced to zero to pass FCC Part 68 in a non-operational mode, e.g. Figure 15. For this
type of design, the series fuse must open before the TISP4xxxM3 fails. For Figure 15, the maximum fuse i2t is 2.3 A2s. In some cases, the
equipment will require verification over a temperature range. By using the rated waveform values from Figure 12, the appropriate series resistor
value can be calculated for ambient temperatures in the range of -40 °C to 85 °C.

The protector characteristic off-state capacitance values are given for d.c. bias voltage, VD, values of 0, -1 V, -2 V and -50 V. Where possible
values are also given for -100 V. Values for other voltages may be calculated by multiplying the VD = 0 capacitance value by the factor given in
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 many applications, such as Figure 16 and Figure 18, 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.
Figure 8 shows the typical capacitance asymmetry; the difference between the capacitance measured with a positive value of VD and the
capacitance value when the polarity of VD is reversed. Capacitance asymmetry is an important parameter in ADSL systems where the
protector often has no d.c. bias and the signal level is in the region of ±10 V.
The protector can withstand currents applied for times not exceeding those shown in Figure 9. Currents that exceed these times must be
terminated or reduced to avoid protector failure. Fuses, PTC (Positive Temperature Coefficient) thermistors 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 9. In some cases, there may be a further time limit
imposed by the test standard (e.g. UL 1459 wiring simulator failure).

Normal System Voltage Levels
The protector should not clip or limit the voltages that occur in normal system operation. For unusual conditions, such as ringing without the
line connected, some degree of clipping is permissible. Under this condition, about 10 V of clipping is normally possible without activating the
ring trip circuit.
Figure 11 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 TISP4265M3BJ, with a VDRM of 200 V, can be used for the protection of ring generators producing
100 V rms of ring on a battery voltage of -58 V (Th2 and Th3 in Figure 18). The peak ring voltage will be 58 + 1.414*100 = 199.4 V. However,
this is the open circuit voltage and the connection of the line and its equipment will reduce the peak voltage. In the extreme case of an
unconnected line, clipping the peak voltage to 190 V should not activate the ring trip. This level of clipping would occur at the temperature
when the VDRM has reduced to 190/200 = 0.95 of its 25 °C value. Figure 11 shows that this condition will occur at an ambient temperature of
-28 °C. In this example, the TISP4265M3BJ will allow normal equipment operation provided that the minimum expected ambient temperature
does not fall below -28 °C.
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 SMBJ 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 worst case condition. The PCBs used in the majority of applications will achieve lower values of thermal resistance, and can
dissipate higher power levels than indicated by the JESD51 values.
