description
The TISP61060 is a dual forward-conducting buffered p-gate overvoltage protector. It is designed to protect monolithic SLICs (Subscriber Line Interface Circuits), against overvoltages on the telephone line caused by lightning, a.c. power contact and induction. The TISP61060
Terminals K1, K2 and A correspond to the alternative line designators of T, R and G or A, B and C. The

limits voltages that exceed the SLIC supply rail voltage.
The SLIC line driver section is typically powered from 0 V (ground) and a negative voltage in the region of
-10 V to -70 V. The protector gate is connected to this negative supply. This references the protection (clipping) voltage to the negative supply voltage. As the protection voltage will track the negative supply voltage, the overvoltage stress on the SLIC is minimised. (see Applications Information).
Positive overvoltages are clipped to ground by diode forward conduction. Negative overvoltages are initially clipped close to the SLIC negative supply rail value. If sufficient current is available from the overvoltage, then the protector will crowbar into a low voltage on-state condition. As the current subsides the high holding current of the crowbar prevents d.c. latchup.

These monolithic protection devices are fabricated in ion-implanted planar vertical power structures for high reliability and in normal system operation they are virtually transparent. The buffered gate design reduces the loading on the SLIC supply during overvoltages caused by power cross and induction.

NOTES: 1. Initially the protector must be in thermal equilibrium with -40°C TJ≤ 85°C. The surge may be repeated after the device returns to
its initial conditions.
2. The rated current values may be applied either to the Ring to Ground or to the Tip to Ground terminal pairs. Additionally, both terminal pairs may have their rated current values applied simultaneously (in this case the Ground terminal current will be twice the rated current value of an individual terminal pair). Above 85°C, derate linearly to zero at 150°C lead temperature.

DEVICE PARAMETERS
general
Thyristor based overvoltage protectors, for telecommunications equipment, became popular in the late 1970s. These were fixed voltage breakover triggered devices, likened to solid state gas discharge tubes. As these were new forms of thyristor, the existing thyristor terminology did not cover their special characteristics. This resulted in the invention of new terms based on the application usage and device characteristic. Initially, there was a wide diversity of terms to describe the same thing, but today the number of terms have reduced and stabilised.
Programmable, (gated), overvoltage protectors are relatively new and require additional parameters to specify their operation. Similarly to the fixed voltage protectors, the introduction of these devices has resulted in a wide diversity of terms to describe the same thing. To help promote an understanding of the terms and their alternatives, this section has a list of alternative terms and the parameter definitions used for this data sheet. In general, the Texas Instruments approach is to use terms related to the device internal structure, rather than its application usage as a single device may have many applications each using a different terminology for circuit connection.
alternative symbol cross-reference guide
This guide is intended to help the translation of alternative symbols to those used in this data sheet. As in some cases the alternative symbols have no substance in international standards and are not fully defined by the originators, users must confirm symbol equivalence. No liability will be assumed from the use of this guide.

APPLICATIONS INFORMATION
electrical characteristics
The electrical characteristics of a thyristor overvoltage protector are strongly dependent on junction temperature, T
. Hence a characteristic value will depend on the junction temperature at the instant of
J
measurement. The values given in this data sheet were measured on commercial testers, which generally minimise the temperature rise caused by testing.
gated protector evolution and characteristics
This section covers three topics. Firstly, it is explained why gated protectors are needed. Second, the performance of the original IC (integrated circuit) based version is described. Third, the performance improvements given by the TISP61060 are detailed.
purpose of gated protectors
Fixed voltage thyristor overvoltage protectors have been used since the early 1980s to protect monolithic SLICs (Subscriber Line Interface Circuits) against overvoltages on the telephone line caused by lightning, a.c. power contact and induction. As the SLIC was usually powered from a fixed voltage negative supply rail, the limiting voltage of the protector could also be a fixed value. The TISP1072F3 is a typical example of a fixed voltage SLIC protector.
SLICs have become more sophisticated. To minimise power consumption, some designs automatically adjust the supply voltage, V supply voltage would be set low, but for long lines, a higher supply voltage would be generated to drive sufficient line current. The optimum protection for this type of SLIC would be given by a protection voltage which tracks the SLIC supply voltage. This can be achieved by connecting the protection thyristor gate to the SLIC supply, Figure 2. This gated (programmable) protection arrangement minimises the voltage stress on the SLIC, no matter what value of supply voltage.
, to a value that is just sufficient to drive the required line current. For short lines the
