Will GaNEXUS Accelerate ON's AI Data Center Growth Story? - TradingView

ON Semiconductor's launch of the GaNEXUS gallium nitride (GaN) power portfolio is poised to become a key catalyst for its expanding AI data center business. Designed to address rising power density, e... Read original →

ON Semiconductor’s GaNEXUS launch signals a systemic redesign of AI data center power architecture, not just a component upgrade. By enabling >60% magnetic size reduction, it forces upstream magnetics and capacitor suppliers to accelerate miniaturization, while compelling XPU platforms to overhaul thermal strategies. Geopolitically, U.S. CHIPS Act incentives for wide-bandgap semiconductors benefit ON’s expansion—but any escalation in U.S.-China export controls targeting GaN epitaxy could expose its reliance on foundries in Taiwan, China. Competitively, TI is fortifying mid-voltage dominance with integrated controllers, while STMicroelectronics leverages SiC-GaN hybrids for high-power segments; ON must rapidly validate its 1200V GaN to defend the high-end. Within 18 months, GaN adoption in 48V intermediate bus architectures will cross a tipping point, triggering a step-change in power chain efficiency—marking not just material substitution, but a paradigm shift in data center energy economics.
