UL Recognized Components 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).

Users should verify actual device performance in their specific applications. A 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 helps prevent 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.

TISP43xxMMAJ/BJ Overvoltage Protector Series 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. Item Telephone Line Surge – Type A FCC Part 68 TIA/EIA-IS-968 Clause 68.302 (b) Clause 4.2.2 Telephone Line Surge – Type B Clause 68.302 (c) Clause 4.2.3 Simplified Surge Generator Fig. 68.302 (a) Figure 4.1 Open Circuit voltage Wave shape Fig. 68.302 (b) Figure 4.2 Short Circuit Current Wave shape Fig. 68.302 (c) Figure 4.3 E T E L O S B O 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.

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 A2 s) and does operate on Type A surges (I2t < 8 A2s) a non-operational pass can be achieved for Type A testing.

TISP43xxMMAJ/BJ Overvoltage Protector Series 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, VDRM, of ±275 V and a protection voltage, V(BO), of ±350 V. Figure 12 shows the TISP4350MM voltages relative to the POTS -269 V peak ringing voltage. -230 -240 200 V +156 V -269 V RINGING PEAK -250 100 V -260 -270 -275 V WORKING VOLTAGE VDRM -280 0 E T E L O S B O -290 -56.5 V d.c. -300 -310 -100 V TISP4350MM -320 -330 -200 V -340 -350 -360 -269 V -300 V AI4XAD PROTECTION VOLT AGE V(BO) -350 V -370 Figure 11. AI4HAEA Figure 12. 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.

TISP43xxMMAJ/BJ Overvoltage Protector Series 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.

Flow A Comment N No tests Y Box A The criterion for box A is if the modem connects to an outside TNV line. The majority of modems will be connected to an outside line, so the answer is yes. The yes path goes to box B. B A Y B E N Y C Box B The criterion for box B is if the equipment has a limit of ≤ 100 A2s at 600 V rms for Test 1. Many interpret this as a fuse with I2t ≤ 100 A2s and often miss the 600 V a.c. breaking requirement. However, the current loop is comp leted by the fuse and other equipment compon ents. To ensure that the fuse I2t sets the equipment performance, the other current loop componen ts, such as the printed wiring (PW), must have higher I2t values than the fuse. Certainly the fuse I2t needs to be lower than 100 A2s but other compon ents, for example IC packaging, may impose a hazard-free limit of 10 A2s. (This conflicts with TIA/ EIA-IS-968 Type A surge pass requirement of 8 A2s.) E T E L O S B O A yes leads to box C and a no to box E. E Y F N I Boxes E and I The criterion for box E is for a minimum telecommunications line cord of No. 26 AWG to be supplied or specified. N Y Fail A yes leads to box F and a no to box I. The criterion for box I is to pass Test 1. If all the four pass criteria of Test 1 are met, this is a yes and the flow goes to box F. A no result fails the equipment.

TISP43xxMMAJ/BJ Overvoltage Protector Series Power Cross Pass Routes (Continued) Flow Comment Boxes C and D The criterion for box C is overcurrent protection that reduces currents above 1.3 A. This requirement is met by a 1 A fuse (a 1 A current fusing rating, not an IEC 1 A current carrying rating). A Y B Y C Modems which pass FCC Part 68 Type B surges and non-operationally pass Type A surges can use a fuse of 1 A or less, so the yes path to box D can be followed. High performance modems which operationally pass both Type A and B surges would need a fuse of greater than 1 A and so follow the no path to box F. F N Y The criterion for box D is a fire enclosure. D E T E L O S B O H N Pass Y Few modems can afford fire enclosures. However, for an internal modem in a known comp uter case, the case may be evaluated as a fire enclosure. A successful case evaluation will give a yes and an equipment pass. More likely, the modem w ill not have a fire enclosure. The no flow goes to box H. F N Y J N Fail Y Boxes F and J The criterion for box F is a pass to clause 6.3.3 requirements. A yes goes to box G and a no goes to box J. G The criterion for box J is to pass Test 5. If all the three pass criteria of Test 5 are met, this is a yes and the flow goes to box G. A no result fails the equipment. Fail G Boxes G and H The criterion for box G is a fire enclosure and spacings (See box D comments). A yes result passes the equipment and a no result leads to box H. Y N H N Y Pass The criterion for box H is to pass Tests 2, 3 and 4. Test 2 is not required if there is overcurrent protection that reduces currents above 1.3 A (See box C). High performance mod ems, using fuses and without fire enclosures, must pass tests 2, 3, possibly 3A if the fuse opens, and 4. For standard modems, using fuses of 1 A or less and without fire enclosures, tests 3, 3A and 4 must be passed. If the two pass criteria of each of the tests performed are met, this is a yes and the equipment passes. A no result fails the equipment.

TISP43xxMMAJ/BJ Overvoltage Protector Series 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. E T E L O S B O 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(BO) TISP4300MM can be used, Figure 17.
