AI servers squeeze MOSFET supply while PC slump tests power component pricing power

Surging AI server demand is skewing Taiwan, China’s power semiconductor capacity toward high-end MOSFETs and PMICs, triggering structural shortages in mainstream segments. Technically, the slow adoption of GaN/SiC due to cost constraints forces reliance on legacy silicon-based devices, extending 8-inch fab lifespans and delaying advanced-node investments. Compliance-wise, tightening U.S. export controls impose dual-layer scrutiny on Taiwanese suppliers—raising implicit operating costs by over 15%. In market dynamics, Infineon and ON Semi are locking in North American hyperscalers, while local players like Alpha & Omega and GMT sacrifice margins for volume via extended payment terms. Over the next 12–24 months, persistent PC weakness will widen pricing divergence: AI-grade components sustain 10–20% premiums, while consumer-grade parts slide into negative-margin territory. This bifurcation won’t reverse—it’s becoming the new supply-chain stratification norm.
