Anotation

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. Est applicable aux diodes a avalanche (ABD) qui representent un type de composants des parafoudres (appeles ci-apres SPDC) utilises lors de la conception et la realisation des parafoudres connectes aux reseaux basse tension de puissance, de transmission et de communication. Les specifications dessais de la presente norme concernent les diodes a avalanche simples a deux bornes. Toutefois, les diodes a avalanche multiples peuvent etre integrees dans un seul boitier defini comme un ensemble de diodes. Chaque diode de cet ensemble peut etre testee selon cette specification. Cette norme contient une serie de criteres dessais pour la determination des caracteristiques electriques des diodes a avalanche. A partir des methodes normalisees dessais decrites ci-apres, les caracteristiques de fonctionnement et les valeurs assignees des diodes a avalanche peuvent etre etablies et verifiees pour des conceptions particulieres.
