Rectifier diodes are a kind of discrete devices. Discrete devices are widely used in consumer electronics, computers and peripherals, network communications, automotive electronics, led display and other fields. Diode manufacturers include: semiconductor diodes: germanium diodes, silicon diodes, compound diodes, etc.
Since the entry barrier of the low-end rectifier diode market is not high, Chinese local companies can join the market with the advantage of low labor cost resources. In the application field of high-end rectifier diodes, there are not many manufacturers of rectifier bridges capable of producing high-reliability rectifier diodes, so they will continue to be dominated by international manufacturers.
China has become the world's largest discrete power device market. The market demand has increased year by year, and it has the advantage of low supply of production factor resources. Therefore, many international semiconductor manufacturers have begun to transfer rectifier diode production lines to China to accelerate market development. The continuous transfer of international industries and the continuous participation of domestic enterprises will make the competition in China's rectifier diode market increasingly fierce, especially in the low-end market.
Rectifier diodes are an important part of semiconductor discrete devices. As China has become the world's largest market for electronic components, China's semiconductor discrete device production also accounts for half of global production. The industry's output has become popular in the vast rural market with the electronic information industry. It will be getting bigger and bigger. At the same time, the continuous innovation of the electronic information industry will gradually bring China's industrial technology to a new height. By then, the industrial market will be expanded globally and production will have a new breakthrough.
The output value of China's rectifier diode industry reached 24.665 billion yuan, an increase of 34%. In 2012, the output value of China's rectifier diode industry reached 18.406 billion yuan, an increase of 38.4%. With the expansion of China's rectifier diode industry, the four major electronic information industry bases in the Pearl River Delta, the Yangtze River Delta, the Bohai Bay region, and some central and western regions have taken shape. The electronic information enterprises in these regions are concentrated, the industrial chain is relatively complete, and they have considerable scale and supporting capabilities.
