description
The TISP2180L is designed specifically for
telephone equipment protection against lightning
and transients induced by a.c. power lines.
These devices will supress voltage transients
between terminals A and C, B and C, and A and
B.
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.

absolute maximum ratings at
25C case temperature (unless otherwise noted)
NOTES: 1. Above 70C, derate linearly to zero at 150C case temperature
2. This value applies when the initial case temperature is at (or below) 70C. 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.

NOTE
4: These capacitance measurements employ a three terminal capacitance bridge incorporating a guard circuit. The third terminal is
connected to the guard terminal of the bridge.

3-pin plastic single-in-line package
This single-in-line package consists of a circuit mounted on a lead frame and encapsulated within a plastic
compound. The compound will withstand soldering temperature with no deformation, and circuit performance
characteristics will remain stable when operated in high humidity conditions. Leads require no additional
cleaning or processing when used in soldered assembly.
