The global market for Wide Bandgap Power (WBG) Semiconductor Devices was estimated to be worth US$ 5279 million in 2024 and is forecast to a readjusted size of US$ 21056 million by 2031 with a CAGR of 21.0% during the forecast period 2025-2031.
This report provides a comprehensive assessment of recent tariff adjustments and international strategic countermeasures on Wide Bandgap Power (WBG) Semiconductor Devices cross-border industrial footprints, capital allocation patterns, regional economic interdependencies, and supply chain reconfigurations.
Wide Bandgap (WBG) semiconductor devices refer to power electronic devices manufactured using wide bandgap materials such as silicon carbide (SiC) and gallium nitride (GaN). These materials possess a wider bandgap compared to traditional silicon-based materials, enabling operation at higher temperatures, voltages, and frequencies. They exhibit lower on-state resistance, higher efficiency, and smaller form factors. WBG devices are widely applied in high-efficiency power conversion, electric vehicles, renewable energy systems, and other fields. We focus on the Silicon Carbide (SiC) and gallium nitride (GaN) WBG Power Devices and Modules in this report.
The global WBG power device market is currently experiencing rapid expansion. Key growth drivers include rising electric vehicle adoption, accelerated deployment of renewable energy, surging demand for high-efficiency power supplies in data centers and high-performance computing, and policy initiatives supporting carbon neutrality and energy transition. Market opportunities lie in EV powertrains, onboard charging, solar-plus-storage systems, and 5G/high-frequency power supplies. Meanwhile, cost reductions through economies of scale and improved manufacturing processes are accelerating WBG adoption. However, challenges remain, such as the high cost of SiC epitaxial wafers and GaN substrates, manufacturing yield and reliability issues, supply chain concentration, and long qualification cycles for certain applications.
In terms of competitive landscape, the SiC device market is currently dominated by STMicroelectronics, onsemi, Wolfspeed, Infineon, ROHM, BYD Semiconductor, Bosch, and United Nova Technology, together accounting for over 85% of global market share. For GaN devices, leading players include Innoscience, Power Integrations, Inc., Efficient Power Conversion Corporation (EPC), Navitas, Transphorm, Infineon (GaN Systems), as well as Renesas Electronics (Transphorm), with applications focused on fast charging, server power supplies, and automotive electronics. With the entry of more IDMs and foundries, alongside the rise of Chinese companies such as Sanan, Silan, and CR Micro, competition is expected to intensify and market shares will gradually diversify in the coming years.
