description
The TISP4290 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.

MECHANICAL DATA
DO-220
2-pin plastic flange-mount 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.
