description
The TISPL758LF3 is an integrated combination
of a symmetrical bidirectional overvoltage
protector and an asymmetrical bidirectional
overvoltage protector. It is designed to limit the
peak voltages on the line terminals of the Lucent
Technologies L7581/2/3 LCAS (Line Card
Access Switches). An LCAS may also be
referred to as a Solid State Relay, SSR, i.e. a
replacement of the conventional electro-
mechanical relay.
The TISPL758LF3D voltages are chosen to give
adequate LCAS protection for all switch
conditions. The most potentially stressful
condition is low level power cross when the
LCAS switches are closed. Under this condition,
the TISPL758LF3D limits the voltage and
corresponding LCAS dissipation until the LCAS
thermal trip operates and opens the switches.
Under open-circuit ringing conditions, the line
ring (R) conductor will have high peak voltages.
For battery backed ringing, the ring conductor
will have a larger peak negative voltage than
positive i.e. the peak voltages are asymmetric.
An overvoltage protector with a similar voltage
asymmetry will give the most effective protection.
On a connected line, the tip (T) conductor will
have much smaller voltage levels than the open-
circuit ring conductor values. Here a symmetrical
voltage protector gives adequate protection.
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
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.

MECHANICAL DATA
D008
plastic small-outline package
This small-outline 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.
