Why is gallium nitride so popular?

Silicon (Si) is currently the main material for semiconductors, but why is gallium nitride so popular? Wu Zhiyi, director of the Institute of Electronics and Optoelectronic Systems of ITRI, said, "Silicon cannot run fast enough in electronics, cannot be used for high frequencies, and cannot withstand high (electrical) voltages, so it is not suitable for high-power components for 5G applications. There are also situations where its physical properties cannot satisfy it.”

Advantages of gallium nitride

High temperature resistance, high frequency and high power, gallium nitride becomes an important candidate

Zhang Yi, Vice President of Jiaotong University, believes that “gallium nitride will have great potential in the application of new materials in the future because of its sophisticated technology and ability to withstand high temperatures. He also pointed out that the Internet of Vehicles is connected to next-generation mobile communication networks such as 6G and 7G. , will be the best application scenario." Since the 5G era requires higher frequency and higher efficiency, the future plasticity of gallium nitride is exciting!

Small size, low heat generation, high wattage

Gallium nitride GaN has the characteristics of small size, low heat generation and high wattage, which makes it very suitable for use in fast charging chargers for consumer electronic products. Although GaN fast-charging chargers on the market are much more expensive than silicon component chargers, many consumers still pay for them in pursuit of better performance. Even mobile phone and accessory manufacturers such as Xiaomi and Samsung have successively launched gallium nitride GaN fast charging chargers.

The rapid popularization of gallium nitride in the fast charge market is inseparable from the help of the surrounding ecology. In terms of controllers, LLC+PFC controller and QR/ACF controller are gradually complete, providing unlimited possibilities for gallium nitride architecture innovation. In addition, silicon carbide diodes have also been widely used in hundred-watt gallium nitride fast charging, and the charger market has made gallium nitride and silicon carbide both commercially available on a large scale.
