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.

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.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in
addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment
declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses
arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60747-5-5 has been prepared by subcommittee 47E: Discrete
semiconductor devices, of IEC technical committee 47: Semiconductor devices.
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.

The text of this standard is based on the following documents:
FDIS Report on voting
47E/332/FDIS 47E/340/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of the parts in the IEC 60747 series, under the general title Semiconductor devices –
Discrete devices, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
