Infineon is betting big on the 800V dc power distribution that seems to become the new standard for AI data centers which is directly relevant for the chips that are made in this fab.
I think (but I have no actual insides), they picked 800V dc for datacenter also because that is commonly used for the DC bus in EVs. So, one can share a lot of components across industries. Also, 800V just kind of works well for power transistors like SiC Fets.
