This March 2025 Cypris research brief analyzes Gallium Nitride (GaN) technology across its major application domains — consumer electronics, power electronics, telecommunications, and emerging fields — while profiling the key U.S. companies driving its commercialization. GaN is at a clear inflection point, with superior efficiency, switching speeds, and power density making it increasingly competitive against silicon in mid-voltage applications, even as Silicon Carbide (SiC) remains dominant at higher voltages. The technology's broader adoption is shaped less by raw performance than by supply chain concentration risk, the need for system-level re-architecture to unlock its benefits, and the evolving economics of wafer-scale manufacturing.
What You'll Find in the Report
GaN and SiC are not rivals — they're optimized for different parts of the power spectrum
Rather than competing head-to-head, GaN excels in the 48V–650V range for applications like AI data centers, fast chargers, and EV on-board systems, while SiC dominates above 800V in traction inverters and grid infrastructure. Understanding this division is essential for making informed technology and vendor selection decisions.

China's control of gallium supply is the single biggest strategic vulnerability in the GaN ecosystem
With China controlling roughly 98% of low-purity gallium and already demonstrating willingness to impose export restrictions, supply chain concentration is an acute geopolitical risk. Companies that proactively diversify their supply chains or align with domestic manufacturing programs will have a meaningful strategic edge.

GaN adoption requires system-level rethinking, not just a component swap
Unlike SiC, which can often replace silicon IGBTs with minimal redesign, GaN's full performance benefits only emerge when engineers rearchitect the broader system around its higher switching speeds and compact form factor. This creates a key differentiator for vendors like Infineon, Navitas, and EPC that offer integrated toolchains and reference designs that reduce that implementation burden.
