INFORMATION

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.
