Automotive Discrete Semiconductor Market Global Report 2026

The automotive discrete semiconductor market size has grown strongly in recent years. It will grow from $19.63 billion in 2025 to $21.19 billion in 2026 at a compound annual growth rate (CAGR) of 7.9%. The growth in the historic period can be attributed to increasing vehicle electrification, rising adoption of electronic control systems, growing automotive semiconductor content, increasing demand for vehicle power management, and expanding integration of automotive electronics.

The automotive discrete semiconductor market size is expected to see strong growth in the next few years. It will grow to $28.31 billion in 2030 at a compound annual growth rate (CAGR) of 7.5%. The growth in the forecast period can be attributed to rising demand for electric vehicles, increasing adoption of advanced battery management systems, growing need for efficient vehicle charging systems, rising demand for high-voltage automotive power components, and increasing deployment of advanced vehicle powertrain systems. Major trends in the forecast period include increasing adoption of silicon carbide power components, rising demand for gallium nitride semiconductor components, growing use of high-efficiency power switching devices, increasing demand for high-temperature semiconductor components, and rising adoption of advanced automotive power management components.

The rising adoption of electric vehicles (EVs) is expected to drive the growth of the automotive discrete semiconductor market in the coming years. Electric vehicles are automobiles powered wholly or partially by electric motors using energy stored in rechargeable battery systems. The adoption of electric vehicles is increasing due to growing environmental concerns, as consumers, businesses, and governments seek to reduce greenhouse gas emissions, improve air quality, and decrease dependence on fossil fuels through cleaner and more sustainable transportation solutions. Electric vehicles are driving significant demand for automotive discrete semiconductors because they rely on a higher number of power semiconductor components for battery management, power conversion, motor control, onboard charging, and thermal management, making discrete semiconductors essential for improving vehicle efficiency, performance, reliability, and fast-charging capabilities. For instance, in January 2025, according to Cox Automotive, a US-based system software company, new electric vehicle sales totaled 102,243 units, representing a 29.9% increase compared with the same period last year. Therefore, the rising adoption of electric vehicles is driving the growth of the automotive discrete semiconductor market.

Major companies operating in the automotive discrete semiconductor market are focusing on developing innovative solutions, such as high-power semiconductor bridge modules, to improve power density, thermal efficiency, and reliability in electric vehicle and industrial power conversion systems. High-power semiconductor bridge modules are integrated power electronic assemblies that combine devices such as MOSFET half-bridges, diode bridges, and thyristor-based rectifier configurations within a single compact package, enabling efficient switching, rectification, and power control in automotive applications such as on-board chargers and direct current to direct current converters. For instance, in January 2023, STMicroelectronics N.V., a Netherlands-based high-tech company, launched five automotive-grade power semiconductor bridges housed in its ACEPACK SMIT package, designed to deliver higher power density and simplify assembly for next-generation electric vehicle systems. The solution includes 650V MOSFET half-bridges, 600V ultrafast diode bridges, and 1200V rectifier and thyristor-based configurations, supporting a broad range of power conversion requirements in EVs and industrial systems. Additionally, the ACEPACK SMIT package enables efficient top-side cooling through direct-bonded copper technology and an exposed metal surface that improves thermal dissipation and system reliability, while also supporting automated assembly processes that enhance manufacturing efficiency.

In June 2024, Renesas Electronics Corporation, a Japan-based semiconductor company, acquired Transphorm Inc. for $339 million. Through this acquisition, Renesas aimed to expand its gallium nitride (GaN) power semiconductor portfolio to improve efficiency in electric vehicle power systems and industrial power conversion applications, enabling higher power density, faster switching, and lower energy losses across a wide range of high-performance applications. Transphorm Inc. is a US-based power electronics company that specializes in providing automotive discrete semiconductor devices.
