This part of IEC 61643 specifies standard test circuits and methods for thyristor surge
suppressor (TSS) components. These surge protective components, SPCs, are specially
formulated thyristors designed to limit overvoltages and divert surge currents by clamping and
switching actions. These SPCs are used in the construction of surge protective devices
(SPDs) and equipment used in Information & Communications Technologies (ICT) networks
with voltages up to AC 1 000 V and DC 1 500 V. This document is applicable to gated or nongated
TSS components with third quadrant (-v and –i) characteristics of blocking, conducting
or switching.
This document contains information on
• terminology;
• letter symbols;
• essential ratings and characteristics;
• rating verification and characteristic measurement;
This document does not apply to the conventional three-terminal thyristors as covered by
IEC 60747-6.

Is applicable to avalanche breakdown diodes (ABDs) which represent one type of surge protective device component (hereinafter referred to as SPDC) used in the design and construction of surge protective devices connected to low-voltage power distribution systems, transmission, and signalling networks. Test specifications in this standard are for single ABDs consisting of two terminals. However, multiple ABDs may be assembled within a single package defined as a diode array. Each diode within the array can be tested to this specification. This standard contains a series of test criteria for determining the electrical characteristics of the ABD. From the standard test methods described herein, the performance characteristics and ratings of the ABD can be verified or established for specific packaged designs.
