Components for Low-Voltage Surge Protective Devices - Part 321: Specification for Avalanche Breakdown Diode (ABD) - Edition 1.0
N 61643-321
Annotation
This part of IEC 61643 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.

Компоненты для низковольтных защитных устройств скачка - часть 321: спецификация для Диода лавинного пробоя (ABD) - выпуск 1.0
Эта часть IEC 61643 применима к диодам лавинного пробоя (ABDs), представляющие один тип компонента защитного устройства скачка (SPDC именуемый в дальнейшем) используемый в проектировании и строительстве защитных устройств скачка, подключенных к низковольтным системам распределения питания, передаче и сетям сигнализации. Тестовые спецификации в этом стандарте для единственного ABDs, состоящего из двух терминалов. Однако многократный ABDs может быть собран в единственном пакете, определенном как диодная матрица. Каждый диод в массиве может быть протестирован к этой спецификации.
