(Main)Semiconductor devices - Discrete devices - Part 5-5: Optoelectronic devices - Photocouplers
Semiconductor devices - Discrete devices - Part 5-5: Optoelectronic devices - Photocouplers
This part of IEC 60747 gives the terminology, essential ratings, characteristics, safety test as well as the measuring method for photocouplers (or optocouplers). NOTE The word "optocoupler" can also be used instead of "photocoupler". This standard replaces the clauses for photocouplers (or optocouplers) described in IEC 60747-5-1, IEC 60747-5-2 and IEC 60747-5-3, including their amendments. The contents for phototransistors and photothyristors in IEC 60747-5-1, IEC 60747-5-2 and IEC 60747-5-3, including their amendments, will be considered obsolete as of the effective date of publication of this standard. NOTE Photocouplers that are certified to the previous version of the photocoupler standard, namely IEC 60747-5-1/2/3, are to be considered in compliance with the requirements and provisions of IEC 60747-5-5.
Dispositifs à semiconducteurs - Dispositifs discrets - Partie 5-5: Dispositifs optoélectroniques - Photocoupleurs
La présente partie de la CEI 60747 donne la terminologie, les performances essentielles, les caractéristiques, les essais de sécurité ainsi que les méthodes de mesures pour les photocoupleurs (ou optocoupleurs). NOTE Le terme "optocoupleur" peut aussi être employé à la place de "photocoupleur". Cette norme remplace les articles pour les photocoupleurs (ou optocoupleurs) décrites dans la CEI 60747-5-1, la CEI 60747-5-2 et la CEI 60747-5-3, y compris leurs amendements. Le texte concernant les phototransistors et les photothyristors dans la CEI 60747-5-1, la CEI 60747- 5-2 et la CEI 60747-5-3 y compris leurs amendements sera considéré obsolète à la date effective de publication de la présente norme. NOTE Les photocoupleurs qui sont certifiés selon la version précédente de la norme sur les photocoupleurs, c'est-à-dire la CEI 60747-5-1/2/3, sont à considérer comme étant en conformité avec les exigences et dispositions de la CEI 60747-5-5.
