Description
The TISP7xxxH3SL limits overvoltages between the telephone line Ring and Tip conductors and Ground. Overvoltages are normally caused by
a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone line.
Each terminal pair, T-G, R-G and T-R, has a symmetrical voltage-triggered bidirectional thyristor protection characteristic. 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.
