IEC 60747-3:2013

Overview

IEC 60747-3:2013 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for discrete semiconductor devices-specifically signal, switching, voltage-regulator, voltage-reference, and current-regulator diodes. This standard defines essential ratings, characteristics, and testing methods to ensure consistency and interoperability in semiconductor diode devices used in electronics applications.

The 2013 edition represents the second edition of IEC 60747-3, incorporating updated technical content and modernized formatting in line with IEC publication styles. It supersedes the first edition from 1985 and its amendments, aligning the standard with current technology and industry practices. IEC 60747-3:2013 should be used in conjunction with the foundational IEC 60747-1:2006 standard, which covers general semiconductor device terms and definitions.
