description

The TISP4290LP is designed specifically for
telephone equipment protection against lightning
and transients induced by a.c. power lines.
These devices consist of a bidirectional
suppressor element connecting the A and B
terminals. They will suppress inter-wire voltage
transients.

Transients are initially clipped by zener action
until the voltage rises to the breakover level,
which causes the device to crowbar. The high
crowbar holding current prevents d.c. latchup as
the transient subsides.

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.

Lead temperature 1.5 mm from case for 10 s T

NOTES: 1. Above 70°C, derate linearly to zero at 150°C case temperature

2. This value applies when the initial case temperature is at (or below) 70°C. The surge may be repeated after the device has
returned to thermal equilibrium.

3. Most PTT’s quote an unloaded voltage waveform. In operation the TISP essentially shorts the generator output. The resulting
loaded current waveform is specified.
