Is now a good time for companies to increase their long-term investments in AI infrastructure?

Onsemi has announced a strategic shift to prioritize power semiconductors for AI data centers, citing power density as the primary constraint for future infrastructure. The company reported $500 million in AI data center revenue for 2026.

Why it matters

As AI system power usage transitions from current levels of 60 kW toward future limits of 1 MW, hardware capable of managing higher power density has become essential to AI scalability. Onsemi aims to capture this growth by integrating new material technologies into its portfolio.

Onsemi targets a $213 billion addressable market, projected to reach $243 billion following the acquisition of Synaptics. Revenue in the AI sector is expected to grow at a 50% compound annual growth rate through 2030.

The players

Onsemi

A semiconductor manufacturer that produces power management chips and image sensors for the automotive, industrial, and AI infrastructure markets.

Synaptics

A developer of human interface hardware, including touch, display, and connectivity semiconductors, targeted for acquisition by Onsemi.

The details

Onsemi is utilizing its GaNEXUS portfolio, which leverages gallium nitride—a semiconductor material that allows for faster electron mobility and higher temperature operation than traditional silicon—to enable efficient power conversion. Additionally, the company is deploying its Embedded Power Platform, which uses wafer-level integration to stack circuits within the semiconductor package, effectively increasing power handling capabilities while reducing the physical footprint of the components.

September 16, 2026: Onsemi held its annual Investor Day.
2026: The company reached $500 million in AI data center revenue.
2030: Target date for achieving $2.5 billion in annual AI data center revenue.

The Tech Race

This strategic pivot positions Onsemi to compete directly in the race to manage the thermal and electrical demands of modern AI server racks. The move extends the company's prior integration efforts, including its previous acquisition of GTAT for silicon carbide manufacturing.

This hardware transition targets infrastructure developers rather than end users, aiming to resolve power constraints that currently limit AI server capacity. Availability of these new power modules will scale alongside the deployment of 200 kW to 1 MW AI clusters expected in the coming years.

The takeaway

Onsemi is betting that its move into gallium nitride and integrated power platforms will secure its place as a lead supplier for high-density AI data centers. Watch the 2030 revenue target of $2.5 billion as a key performance indicator of whether the company successfully scales its infrastructure business.
