Industry Analysis
ON Semiconductor’s GaNEXUS launch is a strategic strike at AI data centers’ power efficiency ceiling, not just another product rollout. Technically, integrating 650V Smart GaN FETs with the Treo control platform shifts power optimization from component-level to system-wide, forcing redesigns in magnetics and thermal solutions. While gallium nitride isn’t yet export-controlled, its potential synergy with EUV processes could prompt new U.S. BIS regulations, raising supply chain friction. By targeting industrial automation and energy infrastructure—rather than competing head-on in consumer fast-charging against Navitas or Wolfspeed—ON pressures Infineon and STMicro to accelerate GaN IDM consolidation. Within 18 months, as AI server PSUs demand >98% efficiency, GaN will dominate 48V intermediate bus architectures, while SiC retains high-voltage grid applications. Packaging hubs in Taiwan, China and Malaysia will become critical risk buffers amid escalating tech decoupling.
