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. These protectors are guaranteed to voltage limit and withstand the listed lightning surges in both polarities.
After a Type A surge the equipment can be non-operational or operational. An operational pass requires the two high current Type A surges
(200 A, 10/160, and 100A, 10/560), to be reduced to within the TISP4xxxL3BJ ratings (50 A, 10/160 and 30 A, 10/560).

After a Type B surge, the equipment must be operational. As the TISP4xxxL3BJ has a current rating of 40 A, it will survive both Type B surges,
metallic (25 A, 9/720) and longitudinal (37.5 A, 9/720), giving an operational pass to Type B surges.

TISP4xxxL3BJ Overvoltage Protector Series
Description (continued)
For metallic protection, the TISP4350L3BJ is connected between the Ring and Tip conductors. For longitudinal protection, two TISP4350L3BJ
protectors are used; one between the Ring conductor to ground and the other between the Tip conductor to ground. The B type ringer has
voltages of 56.5 V d.c. and up to 150 V r.m.s. a.c., giving a peak voltage of 269 V. The TISP4350L3BJ will not clip the B type ringing voltage as
it has a high impedance up to 275 V.
The TISP4070L3BJ should be connected after the hook switch to protect the following electronics. As the TISP4070L3BJ has a high
impedance up to 58 V, it will switch off after a surge and not be triggered by the normal exchange battery voltage.
These low (L) current protection devices are in a plastic package SMBJ (JEDEC DO-214AA 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 in the SMB package, the
100 A 10/1000 TISP4xxxH3BJ series is available.

functional or, if it is faulty, that it has a short circuit fault mode. In the short circuit fault mode, the following equipment is
protected as the device is a permanent short across the line. The equipment would be unprotected if an open circuit fault mode
developed.

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 terminology for the wave forms produced by the ITU-T recommendation K.21 10/700 impulse generator
‡ Values assume the TISP4xxxL3 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. The required value of series resistance for a given wave form 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 wave form the following values result. The minimum total circuit impedance is 800/30 = 26.7 Ω and the
generator’s fictive impedance is 800/100 = 8 Ω. For an inter-conductor connected TISP4xxxL3, this gives a minimum series resistance value of
26.7 - 8 = 18.7 Ω. After allowing for tolerance, a 20 Ω ±5 % resistor would be suitable. The 10/160 wave form only needs to be considered if
the TISP4350L3 is connected from the conductor to ground. In this case, the conductor series resistance is 24 Ω ±5 % per conductor.
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.

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