EN 61643-321:2002

Components for low-voltage surge protective devices - Part 321: Specifications for Avalanche Breakdown Diode (ABD)

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.

Composants pour parafoudres basse tension - Partie 321: Spécifications pour les diodes à avalanche (ABD)

Est applicable aux diodes à avalanche (ABD) qui représentent un type de composants des parafoudres (appelés ci-après SPDC) utilisés lors de la conception et la réalisation des parafoudres connectés aux réseaux basse tension de puissance, de transmission et de communication. Les spécifications d'essais de la présente norme concernent les diodes à avalanche simples à deux bornes. Toutefois, les diodes à avalanche multiples peuvent être intégrées dans un seul boîtier défini comme un ensemble de diodes. Chaque diode de cet ensemble peut être testée selon cette spécification. Cette norme contient une série de critères d'essais pour la détermination des caractéristiques électriques des diodes à avalanche. A partir des méthodes normalisées d'essais décrites ci-après, les caractéristiques de fonctionnement et les valeurs assignées des diodes à avalanche peuvent être établies et vérifiées pour des conceptions particulières.
