OS GSO IEC 61643-321:2014 Scope
This part of IEC 61643 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.
