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. Including: semiconductor diodes: germanium diodes, silicon diodes, compound diodes and so on.

Shang Pu Consulting industry analysts pointed out: by the downstream product development constraints, to further improve performance and reduce system cost is the rectifier diode market development trend. Some mature power semiconductor products have been very low profits, companies only in the global optimization of the value chain composition, to seek low-cost manufacturing resources in order to continue to maintain market position, which contributed to the rectifier diode production line began to large-scale development Country transfer.

As the low-end rectifier diode market entry threshold is not high, the Chinese local enterprises can rely on low labor costs and other elements of resources to join the market. And in the application of high-end rectifier diodes, can produce high-reliability rectifier diode manufacturers are not many, it will continue to be dominated by international manufacturers.

China has become the world's largest discrete power device market, the market demand increased year by year, but also has the advantages of low supply of factors of production resources, so many international semiconductor manufacturers have begun to rectifier diode production line transferred to China to speed up market development efforts. The continued transfer of international industry and the constant addition of domestic enterprises will make the competition of China's rectifier diode market increasingly fierce, especially the low-end market competition will be white-hot trend.

China's rectifier diode started late, technical capacity and business scale are relatively limited. China's rectifier diode enterprise structure of state-owned enterprises, private enterprises, joint ventures (foreign) enterprises, the largest number of private enterprises, the largest output, foreign-funded enterprises in the technical advantages. From the industry development point of view, small and medium-sized private enterprises due to low risk of anti-risk, the future will be part of being eliminated. The number of domestic enterprises will gradually reduce the size of enterprises will gradually expand.

Rectifier diode is an important part of the semiconductor separator, with China as the world's largest electronic components market, China's semiconductor discrete device production also accounted for half of global production, industry output With the electronic information industry in the vast rural market, Will be getting bigger and bigger. At the same time, the continuous innovation of electronic information industry will gradually bring our industrial technology to a new height, when the industrial market will be expanded in the world, there will be a new breakthrough in production.

In 2013, China's rectifier industry output value reached 24.665 billion yuan, an increase of 34%. In 2012, China's rectifier diodes industry output value reached 18.406 billion yuan, an increase of 38.4%.


With the expansion of China's rectifier diode industry, the Pearl River Delta, Yangtze River Delta, Bohai Bay area, part of the central and western regions of the four major electronic information industry base was initially formed. These areas of electronic information companies focus on the industry chain is more complete, with considerable size and supporting capacity.

Electronic information industry in China accounted for the increase in total exports, showing that China's industrial transformation effect show. China's engine as a global economy, endogenous growth momentum makes China's electronics industry than the global semiconductor industry faster growth, while driving the development of rectifier diodes market.

The development of the downstream industry is the most important factor of electronic components, if the demand potential can be fully explored, the industry supply capacity will also be effective play, at present, China has become the world's largest demand for diodes market, but from the market supply in China Degree of view, in addition to technical breakthroughs, almost all can be fully met.
