2 truths and a myth
How well do you know onsemi EliteSiC – can you spot the myth?
Read about how onsemi is addressing the latest developments in residential and commercial battery energy storage systems (BESS) with their EliteSiC products.
6/6
Silicon Carbide products feature lower thermal resistance over standard
silicon devices.
CORRECT
TRY AGAIN
onsemi has assembled the only
end-to-end SiC supply chain.
CORRECT
TRY AGAIN
All SPICE models are created equal.
CORRECT
TRY AGAIN
TRUTH - onsemi’s energy storage SPICE models feature robust and performance optimized SiC discretes, modules, and drivers targeting
the power stage topologies.
Truth
Myth
5/6
SiC solutions are cost-effective from
an overall BOM cost.
CORRECT
TRY AGAIN
The quality standards of SiC products
are lower than standard silicon solutions.
CORRECT
TRY AGAIN
Increasing voltages in EV and solar are
no problem for SiC.
CORRECT
TRY AGAIN
TRUTH - onsemi’s tightly controlled end-to-end supply chain
provides for a very high level of quality and reliability standards
which are unmatched in the industry
Truth
Myth
4/6
SiC designs do not require a negative turn-off gate voltage.
CORRECT
TRY AGAIN
Galvanically isolated gate drivers are
a good choice for SiC designs.
CORRECT
TRY AGAIN
SiC is less robust than silicon IGBTs.
CORRECT
TRY AGAIN
TRUTH - The smaller geometries of SiC mean lower short circuit withstand time, however, the appropriate gate driver ensures the short circuit event
is detected and the device turned off which ensures ruggedness.
Truth
Myth
3/6
SiC FET gate drivers are quite complex.
CORRECT
TRY AGAIN
SiC products are suited for a wide range of applications from low to high-end.
CORRECT
TRY AGAIN
SiC has a well-established and developed ecosystem of support.
CORRECT
TRY AGAIN
TRUTH - The idea that SiC products require complex drivers stems
from early designs where designers needed to develop their own circuits.
Today there are many off-the-shelf drivers for rapid SiC development.
Truth
Myth
2/6
SiC is a reasonable replacement
for silicon IGBTs and MOSFETs.
CORRECT
TRY AGAIN
SiC products are well-suited for both low and higher-frequency applications.
CORRECT
TRY AGAIN
SiC devices are subject to supply-chain restrictions.
CORRECT
TRY AGAIN
TRUTH - onsemi’s robust end-to-end supply and manufacturing chain eliminates concerns over restrictions.
