低压浪涌保护装置的元件 第321部分：雪崩击穿二极管（ABD）规范

[中文适用范围]： IEC 61643的本部分适用于雪崩击穿二极管（ABD），它代表一种浪涌保护器件组件（以下简称SPDC），用于设计和建造连接到低压配电系统、输电系统的浪涌保护器件。和信令网络。本标准中的测试规范适用于由两个端子组成的单个 ABD。然而，多个 ABD 可以组装在定义为二极管阵列的单个封装内。阵列中的每个二极管都可以按照该规范进行测试。该标准包含一系列用于确定 ABD 电气特性的测试标准。根据本文描述的标准测试方法，可以针对特定封装设计验证或建立 ABD 的性能特征和评级。 [外文原描述]： 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.
