Advances in dielectric materials and declining costs are encouraging China MOSFET companies to consider SiC and GAN adoption to update their silicon-based yield.

MOSFETS using silicon dielectric material continue to lead output in China, but there has been a trend toward SiC and GaN units amid the narrowing cost gap. The more advanced types boast low energy loss, quick switching time and high temperature resistance, ensuring ultrasmall and high-efficiency application products.

Local makers, including Global Power and InventChip, are already engaged in the production of SiC and GAN kinds. More companies are expected to follow.

China's typical MOSFET releases come in through-hole and SMD packages such as DIP, TO, PGA, SOT, SOP, QFP, DPAK and PLCC. These are mainly used in home appliances, and consumer electronics, automotive, industrial and aviation applications.

Wafers, the key component in the manufacture of MOSFETs, usually come from local or foreign companies. Due to input supply shortage, overall costs increased in the past year, jacking up MOSFET prices by 10 percent. This trend is likely to persist throughout 2020.

MOSFETs' wide adoption, including in audio devices, UPS, switching power supplies and solar power systems, is the reason the component represents 40 percent of total shipments in the global power devices industry. Power MOSFETs are projected to have a market scale of up to $8.5 billion in 2022, according to Elecfans.

The products in this gallery have been handpicked by our China-based market analyst for representing current trends in MOSFETs from China makers.
