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 doc...view more
