14、the IEEE-SA Standards Board Operations Manual shall not be considered or inferred to be the official position of IEEE or any of its committees and shall not be considered to be, or be relied upon as, a formal position of IEEE.

Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardle
16、ss of membership affiliation with IEEE. However, IEEE does not provide consulting information or advice pertaining to IEEE Standards documents. Suggestions for changes in documents should be in the form of a proposed change of text, together with appropriate supporting comments. Since IEEE standards
17、 represent a consensus of concerned interests, it is important that any responses to comments and questions also receive the concurrence of a balance of interests. For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response
18、 to comments or questions except in those cases where the matter has previously been addressed. For the same reason, IEEE does not respond to interpretation requests.

By publication of this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith.

Introduction This introduction is not part of IEEE Std C62.42.3-2017, IEEE Guide for the Application of Surge Protective Components in Surge Protective Devices and Equipment PortsPart 3: Silicon PN-Junction. PN-junction voltage clamping
41、diodes have one or more PN junctions in a silicon chip. Depending on the PN-junction arrangement the clamping characteristic can be one of five types: forward-biased, Zener, avalanche, punch-through, or fold-back. The chosen component technology for a given application depends on the required clampi
42、ng voltage. Clamping voltages above 10 V dictate the use of avalanche or fold-back technologies. Clamping voltages of 6 V and below are best suited to punch-through or forward-biased technologies. To lower the capacitance, these clamping components are integrated with series diodes or diode bridges.
43、 Making the diode bridge a multi-phase diode bridge allows the protection of multiple conductors with a single clamping protection component. Clause 3 of this document gives the terms used to describe the different types of P-N-junction voltage clamping component and Clause 4 covers the various phys
44、ical PN-junction constructions. Clause 5 deals with the characteristics of the different PN-junction structures and Clause 6 details the component ratings. Clause 7 describes application examples for the protection of ac, dc, or signal circuits and component series and parallel combinations.
