Specifications are subject to change without notice.

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.
The TISP4xxxM3AJ range consists of
twenty 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
medium (M) current protection devices
are in a plastic package SMAJ (JEDEC
DO-214AC with J-bend leads) and
supplied in embossed tape reel pack. For
alternative voltage and holding current
values, consult the factory. For higher
rated impulse currents, the 100 A 10/1000
TISP4xxxH3BJ series in the SMB (JEDEC
DO-214AA) package is available.

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).
Th3
Th1
Th1
Th2
Figure 12. Two Point Protection
Figure 13. Multi-Point Protection
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.

† 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 15 and Figure 16. 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 14. For this type of design, the series fuse must open before the TISP4xxxM3 fails. For Figure 14, 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 11, the
appropriate series resistor value can be calculated for ambient temperatures in the range of -40 °C to 85 °C.

TISP4xxxM3AJ Overvoltage Protector Series
AC Power Testing
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).
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.
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.
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 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 TISP4265M3AJ, 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 TISP4265M3AJ 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.

Legal Disclaimer Notice
This legal disclaimer applies to purchasers and users of Bourns® products manufactured by or on behalf of Bourns, Inc. and its
affiliates (collectively, “Bourns”).
Unless otherwise expressly indicated in writing, Bourns® products and data sheets relating thereto are subject to change
without notice. Users should check for and obtain the latest relevant information and verify that such information is current and
complete before placing orders for Bourns® products.
The characteristics and parameters of a Bourns® product set forth in its data sheet are based on laboratory conditions, and
statements regarding the suitability of products for certain types of applications are based on Bourns’ knowledge of typical
requirements in generic applications. The characteristics and parameters of a Bourns® product in a user application may vary
from the data sheet characteristics and parameters due to (i) the combination of the Bourns® product with other components
in the user’s application, or (ii) the environment of the user application itself. The characteristics and parameters of a Bourns®
product also can and do vary in different applications and actual performance may vary over time. Users should always verify
the actual performance of the Bourns® product in their specific devices and applications, and make their own independent
judgments regarding the amount of additional test margin to design into their device or application to compensate for
differences between laboratory and real world conditions.
Unless Bourns has explicitly designated an individual Bourns® product as meeting the requirements of a particular industry
standard (e.g., ISO/TS 16949) or a particular qualification (e.g., UL listed or recognized), Bourns is not responsible for any
failure of an individual Bourns® product to meet the requirements of such industry standard or particular qualification. Users of
Bourns® products are responsible for ensuring compliance with safety-related requirements and standards applicable to their
devices or applications.
Bourns® products are not recommended, authorized or intended for use in nuclear, lifesaving, life-critical or life-sustaining applications, nor in any other applications where failure or malfunction may result in personal injury, death, or severe property or
environmental damage. Unless expressly and specifically approved in writing by two authorized Bourns representatives on a
case-by-case basis, use of any Bourns® products in such unauthorized applications might not be safe and thus is at the user’s
sole risk. Life-critical applications include devices identified by the U.S. Food and Drug Administration as Class III devices and
generally equivalent classifications outside of the United States.
Bourns expressly identifies those Bourns® standard products that are suitable for use in automotive applications on such
products’ data sheets in the section entitled “Applications.” Unless expressly and specifically approved in writing by two
authorized Bourns representatives on a case-by-case basis, use of any other Bourns® standard products in an automotive
application might not be safe and thus is not recommended, authorized or intended and is at the user’s sole risk. If Bourns
expressly identifies a sub-category of automotive application in the data sheet for its standard products (such as infotainment
or lighting), such identification means that Bourns has reviewed its standard product and has determined that if such Bourns®
standard product is considered for potential use in automotive applications, it should only be used in such sub-category of
automotive applications. Any reference to Bourns® standard product in the data sheet as compliant with the AEC-Q standard
or “automotive grade” does not by itself mean that Bourns has approved such product for use in an automotive application.
Bourns® standard products are not tested to comply with United States Federal Aviation Administration standards generally
or any other generally equivalent governmental organization standard applicable to products designed or manufactured for
use in aircraft or space applications. Bourns expressly identifies Bourns® standard products that are suitable for use in aircraft
or space applications on such products’ data sheets in the section entitled “Applications.” Unless expressly and specifically
approved in writing by two authorized Bourns representatives on a case-by-case basis, use of any other Bourns® standard
product in an aircraft or space application might not be safe and thus is not recommended, authorized or intended and is at the
user’s sole risk.
The use and level of testing applicable to Bourns® custom products shall be negotiated on a case-by-case basis by Bourns and
the user for which such Bourns® custom products are specially designed. Absent a written agreement between Bourns and the
user regarding the use and level of such testing, the above provisions applicable to Bourns® standard products shall also apply
to such Bourns® custom products.
Users shall not sell, transfer, export or re-export any Bourns® products or technology for use in activities which involve the
