BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS
TISP4xxxH3LM Overvoltage Protector Series
TISP4xxxH3LM Overview
This TISP® device series protects central office, access and customer premise equipment against overvoltages on the telecom line. The
TISP4xxxH3LM is available in a wide range of voltages and has a high current capability, allowing minimal series resistance to be used.
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 TISP4350H3LM meets the FCC Part 68 “B” ringer voltage requirement and survives the
Type A and B impulse tests. These devices are housed in a through-hole DO-92 package (TO-92 package with cropped center leg).

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 helps prevent
d.c. latchup as the diverted current subsides.

TISP4xxxH3LM Overvoltage Protector Series
Description (Continued)
This TISP4xxxH3LM range consists of seventeen voltage variants to meet various maximum system voltage levels (58 V to 320 V). They are
guaranteed to voltage limit and withstand the listed international lightning surges in both polarities. These protection devices are supplied
in a DO-92 (LM) cylindrical plastic package. The TISP4xxxH3LM is a straight lead DO-92 supplied in bulk pack and on tape and reel. The
TISP4xxxH3LMF is a formed lead DO-92 supplied only on tape and reel. For lower rated impulse currents in the DO-92 package, the 50 A
10/1000 TISP4xxxM3LM series is available.

TISP4xxxH3LM Overvoltage Protector Series
APPLICATIONS INFORMATION
Deployment
These devices are two terminal overvoltage protectors. They may be used either singly to limit the voltage between two conductors
(Figure 12) or in multiples to limit the voltage at several points in a circuit (Figure 13).

In Figure 12, 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 13, protectors Th2 and Th3 limit the maximum voltage between each
conductor 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.
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 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 rated waveform values from Figure 11, the appropriate series resistor value can be calculated for ambient
temperatures in the range of -40 °C to 85 °C.
AC Power Testing
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).

APPLICATIONS INFORMATION
Capacitance
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 15 and Figure 17, 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.

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 10 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 TISP4260H3LM, 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 17). 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 10 shows that this condition will occur at an ambient temperature of
-28 °C. In this example, the TISP4260M3LM 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 (1.06 ’’) on a side and the other for packages up to 48 mm (1.89 ’’). The LM package 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.
