PC62.37
Standard for Test Methods and Preferred Values for Thyristor Surge Protective Components
This standard sets terms, test methods, test circuits, measurement procedures and preferred result values for silicon thyristor-based surge protective components used for overvoltage or overcurrent or both protection in low-voltage information technology communications system items. The thyristor variants covered are: Unidirectional characteristic Bidirectional characteristic Two terminal (diode) fixed voltage Three or more terminal gate controlled Integrated series diode types for low capacitance.

Test Methods and preferred values for hybrid integrated circuit components containing gas discharge tube and metal oxide varistor technologies
This standard sets terms, test methods, test circuits, measurement procedures, and preferred result values for two-terminal hybrid integrated circuit surge protective components (SPCs) containing gas discharge tube and metal oxide varistor technologies connected either in series or parallel. 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 1000 V and DC 1500 V, to mitigate overvoltage surges. Series connected gas discharge tube and metal oxide varistor configurations are applicable for AC mains surge protection and the tests reflect this use. Parallel connected gas discharge tube and metal oxide varistor configurations are suited to communications line surge protection and the tests reflect this use. This standard contains information on -- terminology; -- letter symbols; -- graphical symbols; -- environments; -- essential ratings and characteristics; -- rating verification and characteristic measurement; -- mechanical requirements and identification; -- preferred values; -- qualification.
PC62.39
Standard for Test Methods and Preferred Values for Self-Restoring Current-Limiter Components Used in Telecommunication Surge Protection
This standard sets terms, test methods, test circuits, measurement procedures and preferred result values for series connected, self-restoring current-limiter components used in low-voltage telecommunication circuit surge protection. It is only applicable for components in telecommunications circuits with sinusoidal ringing voltages up to 150 V rms at 15 Hz to 70 Hz and dc powering voltages up to 400 V. The self-restoring current limiters covered by this standard have the following properties: - Excessive current causes a transition from a low-resistance state to a high-resistance state - Reverts to a low-resistance state when the excessive current ends - Directly operated by the current flow through the component - Solid-state (no moving parts) - Withstands specified levels of impulse - Withstands specified ac voltage levels when in the high-resistance state. Examples of this type of current-limiter technology are positive temperature coefficient (PTC) step function thermistors of ceramic or polymeric material and silicon semiconductor based electronic circuits. This standard does not cover self-restoring current-limiter components used in applications other than low-voltage telecommunication circuit surge protection such as heaters, inrush-current limiters, or sensing devices. Current interrupting type components, which reduce the current to zero by a mechanical circuit break, are not covered by this standard. In this standard, a telecommunications circuit is a circuit that uses metallic conductors to handle the remote transmission of information, such as data, communications, and signaling.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
C62.33-2016

With appropriate component selection, these components could be used for the overvoltage protection of power and signal systems having continuous ac voltages (2.5 V rms to 750 V rms), steady-state dc voltages (3.3 V to 1000 V), and peak signal feed voltages (3.5 V to 850 V).
