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).

TISP43xxMMAJ/BJ Overvoltage Protector Series

Description (Continued)

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.

This TISP43xxMM range consists of three voltage variants targeted at specific applications: ADSL, electro-mechanical hook switch and solid
state hook switch modems. These parts are guaranteed to voltage limit and withstand the listed international lightning surges in both
polarities. Two packages are available; SMB (JEDEC DO-214AA with J-bend leads) and SMA (JEDEC DO-214AC with J-bend leads). These
devices are supplied in embossed tape reel carrier pack. For alternative voltage and holding current values, consult the factory.

APPLICATIONS INFORMATION

FCC Part 68, ACTA, TIA and EIA

From 2001, the registrations for FCC equipment changed from the FCC to ACTA, Administrative Council for Terminal Attachments. For this
function, ACTA needed to adopt a US National standard specifying terminal equipment requirements. The TIA, Telecommunications
Industry Association, in conjunction with the EIA, Electronic Industries Alliance, created TIA/EIA-IS-968 for this purpose. The first issue of
TIA/EIA-IS-968 is essentially a renumbered version of the FCC Part 68 requirement. Clause and figure changes are shown in the table.

TIA/EIA-IS-968 (FCC Part 68) 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 values for the TIA/EIA-IS-968 and ITU-T recommendation K.21.

‡

Values assume the TISP43xxMM is connected inter-conductor and a 400 V primary is used

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. For the new edition of ITU-T recommendation K.21 (2000) some series resistance might
be needed to pass the impulse coordination test. The value for a 400 V primary protector is given in the table.

The required value of device survival 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 TIA/EIA-IS-968 10/560 waveform the following values result. The minimum total circuit impedance is 800/55 = 15 Ω and the
generator’s fictive impedance is 800/100 = 8 Ω. For an inter-conductor connected TISP43xxMM, this gives a minimum series resistance value
of 15 - 8 = 7 Ω. The 10/160 waveform only needs to be considered if the TISP43xxMM is connected from the conductor to ground. In this
case the conductor series resistance is 12.5 Ω per conductor.

Fuse Values for TIA/EIA-IS-968 (FCC Part 68)

Fuses must not operate on the Type B surge. To survive a 37.5 A Type B surge, the fuse needs to have a melting I2t of greater than 0.7 A2s.

To survive the Type A surges a fuse melting I2t value of greater than 10 A2s for 10/160 and 8 A2s for 10/560 is needed. By using a fuse which
does not operate on Type B surges (I2t > 0.7 A2s) and does operate on Type A surges (I2t < 8 A2s) a non-operational pass can be achieved for
Type A testing.

Customers should verify actual device performance in their specific applications.

TIA/EIA-IS-968 (FCC Part 68) System Voltage Levels

The protector should not clip or limit the voltages that occur in normal system operation. If the maximum system voltages are not known, then
designers often used the voltages for the FCC Part 68 “B” ringer. The “B” ringer has a d.c. voltage of 56.5 V and a maximum a.c. ring voltage
of 150 V rms. The resultant waveform is shown in Figure 11. The maximum voltage is -269 V, but, because of possible wiring reversals, the
protector should have a working voltage of ±269 V minimum. The TISP4350MM protector meets this requirement with a working voltage,
V

, of ±275 V and a protection voltage, V

, of ±350 V. Figure 12 shows the TISP4350MM voltages relative to the POTS -269 V peak

ADSL System Voltage Levels

The ADSL signal can be as high as ±15 V and this adds to the POTS signal making a peak value of -284 V. This increased signal value of

-284 V would be clipped by the TISP4350MM, which only allows for a -275 V signal. The TISP4360MM has been specified to overcome this
problem by having a higher working voltage of ±290 V. Figure 13 shows the TISP4360MM voltages relative to the -284 V peak ADSL plus
POTS ringing voltage. The ±15 V ADSL signal is shown as a gray band in Figure 13.

IEC 60950, UL 1950/60950, CSA C22.2 No. 950/60950 and EN 60950

These electrical safety standards for IT (Information Technology) equipment at the customer premise use the IEC (International Electro­technical Commission) 60950 standard as the core document. The IEC 60950 covers fundamental safety criteria such as creepage and
isolation. The connection to a telecommunication network voltage (TNV) is covered in clause 6.

Europe is harmonized by CENELEC (Comité Européen de Normalization Electro-technique) under EN 60950 (included in the Low Voltage
Directive, CE mark). Up to the end of 2000, the US had UL (Underwriters Laboratories) 1950 and Canada CSA (Canadian Standards Authority)
C22.2 No. 950. The US and Canadian standards include regional changes and additions to the IEC 60950. A major addition is the inclusion of
clause 6.6, power cross withstand containing the flowchart Figure 18b and annex NAC covering testing. Remarks made for UL 1950 will
generally be true for CSA 22.2 No. 950.

In December 2000, UL released UL 60950, which will run concurrently with UL 1950 until 2003, after which submittals can only be made for
UL 60950. The equivalent Canadian document is designated CSA C22.2 No. 60950. Changes and differences between UL 1950 and UL
60950 do not affect power cross testing nor evaluation criteria. Clause and figure numbering has changed between the standards and these
changes are shown in the table. In this document, these two standards are being jointly referred to as UL 60950 and the clause and figure
numbering referenced will be from UL 60950.

Fuse Values for UL 1950/60950

Fuses for the UL 1950/60950 power cross need to break the specified currents at 600 V a.c. - ordinary fuses will not do! Fuse specification

terms like short circuit capabilities to UL 1459 and UL 1950/60950, 40 A, 7 A and 2.2 A at 600 V a.c. ensure that the 600 V breaking is met.

The requirement of Figure 14, box B, limits the fuse I2t to less than 100 A2s.

Box C, with its 1.3 A limit gives a flow division. Modems passing the TIA/EIA-IS-968 Type A surge in a non-operational mode, could use a fuse
of 1 A rating or less and satisfy the 1.3 A limit and move to box D. Modems operationally passing the Type A surge will tend to use a 1.25 A
fuse, such as the Bel SMP 1.25, and move to box F. Fuses with ratings of 2 A and above may not operate before the wiring simulator fails
(typically 3 A d.c.).

TISP43xxMM and UL 1950/60950 Power Cross

The TISP43xxMM conducts current for periods greater than the power cross test times, Figure 10, so the TISP43xxMM is not a major factor in
UL 1950/60950 compliance. The main design task for UL 1950/60950 power cross is about enclosure design and the selection of the other
components that are subject to power cross. A UL specified fuse together with a TISP43xxMM gives a simple design approach to meeting the
power cross requirements.

Summary of TISP4350MM, TISP4360MM and TISP4300MM Applications

The TISP4350MM is designed to meet the FCC Part 68 Type B ringer voltages and is suitable for electro-mechanical hook switch POTS
modems, Figure 15. For ADSL modems, the TISP4360MM should be used as it has an increased working voltage to avoid clipping the ADSL
signal, Figure 16. The solid state hook switch used in POTS modems may be limited in voltage and dissipation capability. To reduce the
voltage stress level on the solid state switch, a 300 V V

TISP4300MM can be used, Figure 17.
