TISPL758LF3D
INTEGRATED SYMMETRICAL AND ASYMMETRICAL BIDIRECTIONAL OVERVOLTAGE
PROTECTORS FOR LUCENT TECHNOLOGIES L7581/2/3 LINE CARD ACCESS SWITCHES
JANUARY 1998 - REVISED OCTOBER 1998
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
prevents 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.
These protection devices are supplied in a small-outline surface mount (D) plastic package. The difference
between the TISPL758LF3D and TISPL758LF3DR versions is shown in the ordering information.

NOTES: 1. Above the maximum specified temperature, derate linearly to zero at 150°C lead temperature.
2. Initially the TISPL758LF3 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.
