Full Description

Scope

This application guide applies to Thyristor Surge Protective Components (SPCs)used in systems with voltages up to 1000 Vrms or 1200 Vdc. These components are designed to limit overvoltages and divert surge currents by limiting the voltage and switching to a low impedance state. Although telecommunication circuits are the main application of Thyristor SPCs, this guide will also provide useful information for other protection applications. This guide is intended to complement and be used in conjunction with the IEEE Standard Test Specification for Thyristor Diode Surge Protective Devices (IEEE C62.37).

Purpose

This guide is intended to provide assistance in selecting the most appropriate type of thyristor surge protective component (SPC) for use in a surge protective device (SPD), equipment, or system application. The IEEE Standard Test Specification for Thyristor Diode Surge Protective Devices (ANSI/IEEE C62.37) defines thyristor SPC parameters and their measurement. This guide explains the basic functions, component structures, surge environment, comparative thyristor technologies, how parameters are interpreted and selected for example applications.

Abstract

Revision Standard - Active.Applications information on fixed-voltage and gated-thyristor surge protective components (SPCs) is provided. Key device parameters and their sensitivities are explained. Several worked telecommunication circuit design examples are given.
