Description
The TISP3xxxH3SLL 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.
The protector consists of two symmetrical voltage-triggered bidirectional thyristors. 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.
The TISP3xxxH3SLL range is designed to voltage limit and withstand the listed international lightning surges in both polarities. These high
current protection devices are in a 3-pin long-lead single-in-line (SLL) plastic package and are supplied in tube pack. These monolithic
protection devices are fabricated in ion-implanted planar structures to ensure precise and matched breakover control and are virtually
transparent to the system in normal operation.
