The growing demand for electric vehicles (EVs) is projected to drive the expansion of the silicon carbide (SiC) diode market in the future. Electric vehicles are powered by electric motors and rechargeable batteries, in contrast to traditional internal combustion engines. The rise in EV adoption is driven by environmental concerns, the expansion of charging infrastructure, and government incentives. SiC diodes enhance the efficiency of EVs by reducing switching losses, improving thermal conductivity, and enabling rapid switching capabilities. These improvements reduce the size and weight of power components, leading to better performance and energy efficiency in EV powertrains. For example, in April 2023, the International Energy Agency reported that electric car sales surpassed 10 million in 2022 and are approaching 14 million in 2023, with targets set to increase to 35% by 2030. Thus, the growing demand for EVs is expected to fuel the growth of the SiC diode market.

Leading companies in the SiC diode market are developing advanced products such as third-generation silicon carbide Schottky barrier chips to improve performance and efficiency in high-power applications. Schottky barrier diodes are designed to achieve high breakdown voltage, low forward voltage drop, high switching speeds, and superior thermal conductivity. For instance, in July 2023, Toshiba Electronic Devices & Storage Corporation, a Japan-based electronics company, launched the TRSxxx65H series. This diode features a low forward voltage of 1.2V, which is 17% lower than the previous generation’s 1.45V, significantly enhancing power conversion efficiency. The series can handle forward DC currents (IF(DC)) up to 12A and square-wave surge currents (IFSM) up to 640A, and is available in TO-220-2L and DFN8×8 packages. The diodes utilize an optimized junction barrier Schottky (JBS) structure, which reduces leakage current and power dissipation, making them more effective for industrial applications.
