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.

This TISP4xxxH4BJ range consists of six voltage variants to meet various maximum system voltage levels

(135 V to 270 V). They are guaranteed to voltage limit and withstand the listed international lightning surges

in both polarities. These high (H) current protection devices are in a plastic package SMBJ (JEDEC DO-

214AA with J-bend leads) and supplied in embossed carrier reel pack. For alternative voltage and holding

current values, consult the factory. For lower rated impulse currents in the SMB package, the 50 A 10/1000

TISP4xxxM3BJ series is available.
