Market Growth Factors

The global super junction MOSFET market is increasingly driven by the automotive industry’s shift towards electric vehicles (EVs) and hybrid electric vehicles (HEVs). According to the report, the global automotive electronics market size was estimated at USD 342.55 Billion in 2024. Super junction MOSFETs are key in power management systems such as battery management, inverters, and charging infrastructure. Their ability to handle higher voltages and superior heat dissipation capabilities make them ideal for automotive use. The rising adoption of modern driver-assistance systems (ADAS) and electric power steering systems further enhances demand for these efficient power devices.

Renewable energy applications are another crucial market driver. The report highlights significant demand from solar inverters and wind turbines, where efficient power conversion is essential. Super junction MOSFETs improve energy efficiency by reducing power losses during the transfer of renewable energy into usable electricity. Deloitte's 2024 survey also notes 97% of utilities focusing on clean and renewable energy to support data center expansions. Government policies and environmental concerns favor the shift toward renewables, increasing reliance on these power devices to ensure sustainable energy systems.

Technological advancements contribute significantly to the market. Manufacturers are implementing innovations in epitaxy growth and substrate materials, producing devices with lower on-resistance and enhanced voltage handling. For instance, in June 2024, Infineon Technologies launched a 600V super junction MOSFET featuring a built-in temperature sensor for automotive power management, improving precision by 40% and response time by four times compared to conventional sensors. Developments in materials like silicon carbide (SiC) bolster performance in high-voltage applications, meeting the demand for compact and efficient power solutions. These advances reduce costs and improve accessibility, supporting sustained market growth.
