Power Transistor Global Market Report 2026

Power transistors are semiconductor components designed to manage and regulate high levels of voltage and current, allowing efficient switching and amplification in applications such as power supplies, motor drives, and electronic circuits. Engineered to handle substantial power loads while ensuring efficiency and thermal stability, they play a vital role in maintaining reliable performance in high-power and energy-intensive systems.

The primary categories of power transistors include bipolar junction transistors, field-effect transistors, heterojunction bipolar transistors, and others. A bipolar junction transistor (BJT) is a semiconductor device that employs both electrons and holes as charge carriers to switch or amplify electrical signals. These transistors are produced using technologies such as low-voltage field-effect transistors, RF and microwave power devices, high-voltage field-effect transistors, and insulated gate bipolar transistors. They are available in different power ratings, including low power (below 40 volts), medium power (40 to 600 volts), and high power (above 600 volts). Power transistors serve a wide range of end-user industries, including automotive and electric or hybrid electric vehicles, consumer electronics and mobile devices, industrial automation and motor drives, energy and power, data centers and high-performance computing, telecom and 5G infrastructure, as well as aerospace and defense.

Interest in EVs is rising as they help reduce carbon emissions and promote environmentally friendly transportation. Power transistors play a vital role in electric vehicles by managing and switching high voltages and currents, ensuring efficient motor speed control, power delivery, and battery usage. For example, in June 2024, the International Council on Clean Transportation (ICCT), a US-based nonprofit research group, reported that sales of new electric light-duty vehicles in the United States reached around 1.4 million in 2023, up from nearly 1 million in 2022, accounting for about 9% of total new vehicle sales. As a result, the increasing focus on electric vehicles is boosting demand for power transistors.

Companies in the power transistor market are developing advanced innovations, such as input or output figures-of-merit (FOMs), to enhance device performance, improve energy efficiency, and minimize power losses in high-voltage applications. Figures-of-merit (FOMs) are performance benchmarks used to measure the efficiency, speed, and energy-handling capabilities of power transistors during operation. For instance, in June 2024, Infineon Technologies AG, a Germany-based semiconductor manufacturer, introduced its CoolGaN 700V G4 power transistor family, which delivers highly efficient power conversion up to 700V. This product offers significant performance improvements compared to other gallium nitride (GaN) devices, resulting in higher efficiency, lower power losses, and more cost-effective solutions for a wide range of applications. The launch aims to provide superior GaN-based power solutions for high-voltage use cases.
