The growing demand for electric vehicles (EVs) is expected to propel the growth of the wide-bandgap power semiconductor market going forward. Electric vehicles refer to automobiles powered by electric motors that utilize energy stored in rechargeable battery systems instead of conventional internal combustion engines. The demand for electric vehicles is increasing due to stringent emission regulations, as governments worldwide are implementing stricter carbon reduction policies to address climate change and promote cleaner transportation solutions. Wide-bandgap power semiconductors support electric vehicles by enabling efficient power conversion, reducing switching and conduction losses, supporting faster charging capabilities, and improving vehicle driving range and thermal performance through compact, high-temperature-resistant power electronic systems. For instance, in January 2025, according to Cox Automotive, a US-based system software company, full-year electric vehicle sales reached 1.3 million units in 2024, representing a 7.3% increase compared to the revised figures for 2023. Therefore, the growing demand for electric vehicles (EVs) is contributing to the growth of the wide-bandgap power semiconductor market.

Companies operating in the wide-bandgap power semiconductor market are focusing on developing innovative solutions, such as gallium nitride (GaN) power transistors with integrated Schottky diodes, to enhance power conversion efficiency, reduce switching losses, and improve overall system performance in high-voltage and high-frequency applications. Gallium nitride (GaN) power transistors with integrated Schottky diodes are advanced wide-bandgap semiconductor devices that combine high electron mobility and fast switching capability with an integrated diode structure, minimizing reverse recovery losses and eliminating the need for external diode components compared with conventional silicon-based power transistors. In April 2025, Infineon Technologies AG, a Germany-based power semiconductor company, launched an industrial gallium nitride (GaN) transistor product family with an integrated Schottky diode under its CoolGaN G5 portfolio. The new devices are designed to reduce dead-time losses in hard-switching applications, significantly enhancing system efficiency in power electronics. Additionally, the integration of the Schottky diode simplifies power stage design by eliminating the need for external diode components, thereby reducing design complexity and overall system cost. The product is targeted at high-efficiency applications including server and telecom power systems, USB-C fast chargers, and industrial motor drives.
