Such components are u

30、sed in the construction of surge protective devices, particularly as they apply to telecommunications. This standard contains information on - terms, letter symbols, and definitions - basic functions, configurations and component structure - service conditions and fault modes - rating verification a

41、 60747-6) and rectifier diode (IEC 60747-2) standards. NOTE 1 IEC 60747-1, chapter V, clause 2.1 .I, states “IEC 60027 recommends the letters V and v only as reserve symbols for voltage; however, in the field of semiconductor devices, they are so widely used that in this publication they are on the

42、same plane as U and u.“ This standard uses the letters V and v for voltage with the letters U and u as alternatives. NOTE 2 When several distinctive forms of letter symbol exist, the most commonly used form is given first. 3.1.1 main terminal ratings listed ratings cover the appropriate requirements
