greater power density and miniaturization
the market needs from
power products to meet growing
environmental concerns. Alternatively,
WBG power devices are gaining
traction in the market because
of their energy efficiency and ability
to address many of the environmental
issues. For example, silicon carbide
(SiC) and gallium nitride (GaN)
devices, which enable superior overall
performance, are helping manufacturers
attain remarkable gains
in applications like traction inverters
and adaptors/chargers. Concurrently,
he thinks silicon (Si) products will co-exist with
the WBG products owing to their cost-effectiveness in
some low-power applications or in systems where performance
is adequate for the application. As a manufacturer
of WBG and Si power products, ST is in a unique position
to deliver power transistors suitable for an application,
noted the speaker.

energy storage programs on native
American tribal lands. Under the
title " Maturing Wide Bandgap Semiconductors
Fosters Standardization, "
Dr. Butler analyzed the newly
released GaN based standards JEP180
and JEP182, looking deeper into GaN
RDS(on) and transient behaviors.
These standards will show how
standards for reliability, characterization,
and datasheet parameters
should be considered together, noted
Dr. Butler. She added, JC-70 committee
is now exploring similar standards
for space and military applications.
Likewise, speaking on the subject of WBG standardization,
Dr. Friedrichs highlighted the threshold voltage
and reverse recovery attributes of SiC devices and how
recently published standards, JEP183 and JEP184, will
enable users to accurately characterize them. Dr. Friedrichs
also highlighted the on-going work aimed at standards for
automotive applications.
There are currently 574 native American federally recwere
delivered. While Dr. Butler, JC-70 chair, and Dr.
Peter Friedrichs, JC-70 cochair and vice president SiC at
Infineon Technologies, jointly investigated the WBG
standardization efforts at JEDEC JC-70 committee, Dr.
Stanley Atcitty, distinguished member of technical staff
at Sandia National Laboratories, described the DOE
ognized tribes in the United States with a population
of 6.79 million. Each tribe is a sovereign nation with its
own government, traditions, culture, etc., and has a unique
relationship with the federal and state governments. Tribal
lands total about 5.8% of land area in the contiguous
United States. These lands have utility-scale renewable
