Compared to other power modules and devices like Power Diode and Thyristors, the Power Transistor market is one of the major parts of the semiconductor industry that serves a variety of applications. Let us look at the current market trends of Power Transistors in 2023 and list possible advancements in their high-power applications.

A Power Transistor is a power semiconductor device that works efficiently under a high voltage and current rating. It has a high power rating and does not overheat or get damaged while serving the power electronics industry. While the semiconductor industry focuses on reducing the transistor size to meet the expectations of Moore's Law, the Power Transistor market centers around dynamic ON-state resistance and high switching capabilities without heat damage.

Power transistor market history

In 2010, according to various market reports, and studies,

• Power MOSFET dominated the power transistor sector with 53 % of the market share.

• IGBT was the second most dominant power transistor accounting for 27 % of the market share.

• RF Amplifier occupied the third position at 11 % of the power transistor market share.

• Power BJT was in the fourth position occupying only 9 % of the power transistor market share.

Up to 2010, the “big four” power transistors dominated the market. Other power transistors like Low-voltage FETs, IGBT modules, microwave transistors, and high-voltage FETs were slowly becoming popular in the industries.

Power transistor market current status

Future development in power transistors

There are several advancements in the semiconductor industry to reduce the transistor size, deal with quantum effects, and improve efficiency. The recent developments of RibbonFET by Intel and CasFET by Purdue Researchers have added value to the industry. But there has been less development in the Power Transistor industry because Power MOSFET and IGBT continue to serve multiple applications with efficiency for decades.

While Power MOSFET has been the “undisputed king” of the discrete power transistor market, IGBT and FETs have emerged among the top contenders. Researchers are shifting their focus to developing Gallium Nitride Power Transistors. Since 2000, GaN transistor development has witnessed good growth because of its advantages over Silicon-based transistors. Infineon Technologies has developed GaN HEMT (Gallium Nitride High-Electron Mobility Transistor) to reduce small capacitances, and enable passive cooling in high-speed switching applications. The global GaN semiconductor market stands at USD2.17 billion as of 2022 and is expected to obtain a high CAGR of 25.4 % from 2023 to 2030. Out of which GaN power market is expected to reach USD1.1 billion in 2026.
