Discrete Component Manufacturers Announce Significant Capacity Expansions Across Asia
Leading manufacturers of MOSFETs, IGBTs, and diodes in East Asia are reportedly initiating substantial capacity expansions, with projected online dates spanning late 2026 through early 2028. This move aims to address lingering supply constraints and future demand growth, particularly from the automotive and industrial sectors.
Major discrete component manufacturers across East Asia, including key players in Japan, South Korea, Taiwan, and mainland China, are embarking on substantial capacity expansion projects for power MOSFETs, IGBTs, and various diode types. These expansions are strategically aimed at mitigating the persistent supply bottlenecks that have characterized the power semiconductor market in recent years and to prepare for an anticipated surge in demand from critical applications like electric vehicles (EVs), renewable energy infrastructure, and advanced industrial automation.
Several large-scale projects are currently underway, with new fabs and expanded production lines projected to come online iteratively between late 2026 and early 2028. Analysts suggest that the aggregated investment signals a collective commitment from manufacturers to stabilize the market and shorten lead times, which have seen significant fluctuations. The focus is not solely on increasing wafer starts but also on enhancing backend assembly and test capacities, which have often been unforeseen choke points in the supply chain.
This concerted capacity boost is expected to gradually ease pressure on procurement teams, with initial benefits likely to be observed in Q4 2027 as new facilities reach full operational efficiency. While short-term lead times may remain elevated for specific high-power or niche discrete components, the long-term outlook for availability and pricing stability is improving. Procurement managers should monitor these developments closely, as strategic long-term agreements (LTAs) with these expanding suppliers could offer significant advantages.
The regional concentration of these expansions in highly industrialized East Asian economies underscores the existing infrastructure advantages and skilled labor pools in these regions. However, it also highlights the potential for geopolitical or localized disruptions to affect a significant portion of the global discrete component supply if diversified manufacturing footprints are not simultaneously pursued by individual companies. As capacity comes online, competition among suppliers is also expected to intensify, potentially leading to more favorable terms for buyers in the longer run.
