PC62.38 - Test Methods and preferred values for hybrid integrated circuit components containing gas discharge tube and metal oxide varistor technologies
Project Details
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.
