What it does

onsemi makes power semiconductors (including silicon carbide) and image and other sensors, used mainly in electric vehicles, cars and industrial equipment, and increasingly in data-center power supplies.

Why it matters

It describes AI data centers as its fastest-growing business and is working with NVIDIA on 800-volt DC power architectures, but automotive and industrial markets still make up most of its sales, so AI is a growing rather than primary driver. It is on the map as an SMH holding with a data-center power role.

How it makes money

Automotive, industrial and data-center equipment makers pay it for power chips, analog and mixed-signal chips, and image sensors.

Geography

United States (Scottsdale, Arizona)

AI stack position

Chip manufacturing, memory and packaging. The foundries, memory makers, and packaging and testing businesses that physically manufacture AI chips. This is where a chip design actually becomes a real, physical piece of silicon.

Same-layer peers

Same-layer peers share an editorial stack classification; that alone does not establish direct competition.
