Cohu, a global supplier of equipment and services optimizing semiconductor manufacturing yield and productivity, announced that a leading semiconductor manufacturer has placed multiple orders totaling approximately $5 million for the DiamondX platform, delivering high-current capability, ultra-low resistance measurement accuracy and scalable multi-site throughput. The systems will support the development and manufacturing of next-generation gallium nitride (GaN) power devices used in AI data center power architectures.
The orders expand Cohu’s position in the fast-growing AI data center market and reflects the ability of our product portfolio to meet the rising demand for higher-power and higher-efficiency power conversion as server power density and thermal constraints increase.
As AI accelerators and high-performance processing nodes drive higher power densities, data center operators are re-architecting power delivery to improve efficiency. GaN power devices play a central role in this transition, and Cohu’s test platforms are designed to support the full lifecycle of GaN adoption, from early development through high-volume deployment.
Cohu’s DiamondX test configurations for power devices enable high-precision characterization and production testing of GaN devices used across key AI data center power stages, including AC-DC front-end conversion, high-voltage DC-DC modules and advanced point-of-load power management ICs.
“AI data centers are fundamentally changing the performance requirements for power semiconductors,” said Luis Müller, Cohu President and CEO. “GaN devices offer compelling efficiency and power density advantages, and the DiamondX platform enables customers to test accurately and economically at scale as they move from device characterization to high-volume production.”
Cohu continues to invest in advanced power test architectures, aligning its roadmap with customer needs for enabling the next wave of AI infrastructure as well as across the industrial and automotive electrification markets.
