Description
This device is 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 device consists of a symmetrical voltage-triggered bidirectional thyristor. Overvoltages are initially clipped by breakdown clamping. If
sufficient current is available from the overvoltage, the breakdown voltage will rise to the breakover level, which causes the device to switch
into a low-voltage on-state condition. This switching action removes the high-voltage stress from the following circuitry and causes the current
resulting from the overvoltage to be safely diverted through the device. The high holding (switch off) current helps prevent d.c. latchup as the
diverted current subsides. This device is designed to voltage limit and withstand the listed lightning surges in both polarities.

TISP4310T3BJ Overvoltage Protector
Description (Continued)
After a TIA-968-A 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 TISP4310T3BJ connected between
the Ring and Tip wires (and without overvoltage protection to ground), the longitudinal 10/160 surge applied to both Ring and Tip will not
activate the TISP4310T3BJ, giving an operational pass. The metallic 10/560 surge is applied between Ring and Tip wires and will operate the
TISP4310T3BJ. As the TISP4310T3BJ has a current rating of 100 A 10/560, it will survive the TIA-968-A Type A 100 A 10/560 metallic surge,
giving an operational pass.
After a TIA-968-A Type B surge, the equipment must be operational. The 9/720 wave shape is used for both longitudinal surges and metallic
surges. For modems with a TISP4310T3BJ connected between the Ring and Tip wires (and without overvoltage protection to ground), the
longitudinal 9/720 surge applied to both Ring and Tip will not activate the TISP4310T3BJ, giving an operational pass. The metallic 9/720 surge
is applied between Ring and Tip wires and will operate the TISP4310T3BJ. As the TISP4310T3BJ has a current rating of 120 A 9/720, it will
survive the TIA-968-A Type B 25 A 9/720 metallic surge, giving an operational pass.
The TIA-968-A B-type ringer has voltages of 56.5 V d.c. and up to 150 V rms a.c., giving a peak voltage of 269 V. The TISP4310T3BJ will not
clip the B-type ringing voltage, as it has a high impedance up to 269 V.
