Rated for International Surge Wave Shapes

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 TIA/EIA-IS-968 (replaces FCC Part 68) Type A surge the equipment can be faulty, provided that the fault mode causes the equipment to

be unusable. There are two wave shapes used: 10/160 for longitudinal surges and 10/560 for metallic surges. For modems with a

TISP4350T3BJ connected between the Ring and Tip wires (and without overvoltage protection to ground), the longitudinal 10/160 applied to

both Ring and Tip will not activate the TISP4350T3BJ, giving an operational pass. The metallic 10/560 is applied between Ring and Tip wires

and will operate the TISP4350T3BJ. As the TISP4350T3BJ has a current rating of 100 A, 10/560 it will survive the FCC Part Type A 100 A,

10/560 metallic surge giving an operational pass.
