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 whic h ar e ind uc ed or co ndu cte d on to the telephone li ne. A
single device provides 2-point protection and is typically u sed for the protec tion of 2 -wire tel ecommunicatio n
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).
PRODUCT INFORMATION
Information is current as of publication date. Produc ts conform to specifications in accordance
with the terms of Power Innovations standard warranty. Production processing does not
necessarily include testing of all parameters.
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 cu rrent prevents d.c. latchup
as the diverted current subsides.
This TISP4xxxM3LM range consis ts of thirteen voltage variants to meet various maximum system voltage
levels (58 V to 300 V). They are guaranteed to voltage limit and withstand the listed intern ational lightning
surges in both polar ities. Th ese protec tion devices are su pplied i n a DO-92 (LM) cylin drical plastic package.
The TISP4xxxM3LM is a straight lead DO-92 supplied in bulk pack and on tape and reeled. The
TISP4xxxM3LMF is a formed lead DO-92 supplied only on tape and reeled.
