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 to 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.
This TISP4xxxF3LM range consists of ten voltage variants to meet various maximum system voltage levels
(58 V to 270 V). They are guaranteed to voltage limit and withstand the listed international lightning surges in
both polarities. These protection devices are supplied in a DO-92 (LM) cylindrical plastic package. The
