Power Transistors Market Size

Power Transistors Market size was over USD 15.5 billion in 2024 and is estimated to reach USD 30.4 billion by the end of 2037, expanding at a CAGR of 5.8% during the forecast timeline, i.e., 2025-2037. In 2025, the industry size of power transistors is assessed at 16.4 billion.

The rise of electric vehicles (EVs) is a major driver for the power transistors market. EVs rely on these components for power conversion and efficient energy management within battery systems and motor drives. Power transistors enhance vehicle performance, battery life, and energy efficiency, making them essential in EV powertrains. With global initiatives to reduce carbon emissions, the EV market is set to expand, thereby boosting demand for power transistors in automotive applications. According to NZE, in order to attain Net Zero by 2050, the number of EVs worldwide must reach 790 million by 2035, and EV sales must increase to 95% of all vehicle sales by that year.

Moreover, the shift towards industrial automation drives demand for power transistors, especially in advanced manufacturing and robotics. Power transistors enable efficient power regulation and conversion in automated machinery, helping to maintain operational efficiency and reduce energy costs. A PWC analysis estimates that by 2030, automation in three major industries, including manufacturing, will boost the world economy by USD 15 trillion. As industries increasingly adopt automation technologies, the need for reliable power management solutions grows, with power transistors providing essential support for precise and durable power handling.
