General Information
Frequently Asked Questions
WG 8 is a Technical Committee within the International Electrotechnical Commission (IEC). It is named "TC 47/WG 8". This committee has published 324 standards.
WG 8 develops IEC standards in the area of Information technology. Currently, there are 324 published standards from this technical committee.
The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC 63505:2025 gives guidance on VT measurement methods and conditioning prior to VT testing in SiC power MOSFETs to reduce or eliminate the effect of the aforementioned hysteresis. The method is applicable for PBTI testing, NBTI and threshold voltage changes caused by switching events are excluded from the scope.
SiC MOSFETs have threshold voltage hysteresis caused by transient trap effects, which impacts the evaluation of the actual the VT shift caused by stress tests such as bias temperature instabilities (BTI).
