TISPL758LF3D LCAS Protector
Description (Continued)
Overvoltages are normally caused by a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone
line. These overvoltages are initially clipped by protector 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. For negative surges, the high crowbar holding current helps prevent d.c. latchup with the SLIC current, as the surge current
subsides. The TISPL758LF3 is guaranteed to voltage limit and withstand the listed international lightning surges in both polarities.
Support from the Microelectronics Group of Lucent Technologies Inc. is gratefully acknowledged in the definition of the TISPL758LF3D voltage
levels and for performing TISPL758LF3D evaluations.

NOTES: 1. Above the maximum specified temperature, derate linearly to zero at 150 °C lead temperature.
2. Initially the TISPL758LF 3 must be in thermal equilibrium with 0 °C < TJ <70 °C.
3. The surge may be repeated after the TISPL758LF3 returns to its initial conditions.
