Infineon Technologies AG has introduced its first gallium nitride (GaN) transistor family qualified to the Automotive Electronics Council (AEC) standard, marking a major milestone in the company’s strategy to strengthen its position as a global leader in automotive semiconductors and become a key player in GaN technology.

The new CoolGaN Automotive Transistor 100 V G1 family is now in production, with samples of pre-production devices already being supplied to customers. These products, qualified according to the AEC-Q101 standard, include both high-voltage CoolGaN automotive transistors and bidirectional switches. The launch underlines Infineon’s commitment to developing innovative semiconductor solutions that meet the evolving demands of next-generation vehicles.

“Infineon will advance its world-leading position for semiconductor solutions in the automotive industry by bringing GaN power technology to the growing software-defined and electric vehicle market,” said Johannes Schoiswohl, Head of the GaN Business Line at Infineon. “Our 100 V GaN auto transistor solutions and upcoming high-voltage extensions are an important milestone toward energy-efficient and reliable automotive power transistors.”

With the rise of electric and software-defined vehicles, features such as advanced driver assistance systems (ADAS), new infotainment platforms, and enhanced climate control are driving the need for more efficient power management. GaN devices enable higher energy efficiency, reduced system size, and lower overall cost compared to traditional silicon solutions.

As automotive architectures transition from 12 V to 48 V systems, GaN-based power converters are playing a vital role in improving vehicle performance and supporting advanced features such as steer-by-wire and real-time chassis control. Infineon’s new 100 V CoolGaN transistors deliver high efficiency in a compact form factor, making them ideal for zone control units, main DC-DC converters, high-performance auxiliary systems, and Class D audio amplifiers.

Infineon plans to continue expanding its range of automotive-qualified GaN products to further accelerate the adoption of GaN technology in electric and intelligent vehicle applications. The new CoolGaN Automotive Transistors 100 V G1 series, including models IGC033S10S1Q and IGB110S10S1Q, is now available.
