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).
MODEM Protection against:
- TIA/EIA-IS-968 Type A & B surge
(formally FCC Part 68)
- UL 60950, Clause 6. power cross
- CSA 22.2 No. 60950, Clause 6. power cross

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.
