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.North America was the largest region in the power transistor market in 2025.
