are experiencing lead times exceeding 52 weeks,
resulting in all kinds of issues, including product
price increases, scalpers hoarding and reselling
parts at extortionate prices, and even counterfeit
parts entering the market.
For its SiC devices, Microchip has established
multiple fabrication facilities while securing multiple
sources for raw materials. For example, Microchip
has several suppliers for SiC epitaxial wafers and
is not reliant on competitors for these materials.
Therefore, Microchip's fabrication facilities have
significant resistance against global markets,
helping to secure stable supplies of SiC devices for
designers.
Additionally, Microchip offers market-leading lead
times, which not only help to ensure a steady
supply of SiC devices but also equip engineers to
quickly scale up production rates.

Compared to Si, SiC devices have better
reverse recovery charge, greater operating
temperature range, and larger operating
voltages which all contribute to a more
robust component. A product designed using
SiC will have reduced losses, mass, and
volume. In an EV system, this high efficiency
of the SiC-based inverter allows the size of
an EV system battery to be reduced without
affecting the driving range."
