Infineon Technologies unveiled its first gallium nitride (GaN) transistor family qualified to the Automotive Electronics Council (AEC) standard for automotive applications.
The company has begun supplying samples of the CoolGaN Automotive Transistor 100 V G1 family, which adheres to AEC-Q101 standards and includes high-voltage CoolGaN Automotive Transistors and bidirectional switches.
These innovations cater to the increasing demand for efficient power conversion solutions in automotive features such as advanced driver assistance systems, modern climate control and infotainment systems, all of which require higher power outputs while minimizing battery strain.
The use of GaN in semiconductor materials facilitates higher energy efficiency with a smaller form factor and reduced system costs compared to traditional silicon-based components. The shift from 12-V to 48-V systems in software-defined vehicles enhances performance and supports advanced features such as steer-by-wire and real-time chassis control, thus improving ride comfort and handling.
Infineon's 100-V CoolGaN transistors, known for their high efficiency and compact design, are suitable for applications such as zone control and main DC-DC converters, high-performance auxiliary systems and class D audio amplifiers. The CoolGaN Automotive Transistors 100 V G1 family is available.
