Marking and Identification of SMD/chip diodes

1. SMD diode model marking and polarity identification

The model of SMD diode is marked with letters, numerical codes or letter + numerical code marking method and color (code) marking method.

For example, the electrical parameters of the printed word "A3" are as follows: PD=0.15W; IF=0.1A; VB=80V; Trr=4ns. In the color labeling method, the model is mainly found by the color marked on the negative side, and then the parameter value is found by the model.

SMD diode polarity identification method: glass tubular SMD diode, the red end is the positive electrode, the black end is the negative electrode; the rectangular SMD diode, the one end with the white horizontal line is the negative electrode.

2. SMD diode quality measurement

A normal SMD diode, measured on the circuit, has a small forward resistance and a large reverse resistance, and there is a significant difference in resistance between the two. Disconnect the circuit, if measured with a pointer multimeter, the forward resistance is about 3kΩ, and the reverse resistance is hundreds of kiloohms or infinity; The voltage drop is infinite.

3. SMD diode identification on board

On the circuit board, the component number of SMD diode generally starts with the letter D, such as D1, D2, etc., or VD, such as VD1, VD2, etc.; or DD, such as DD1, DD2, etc.

The future development trend of China's semiconductor diode industry

1. Wide-bandgap semiconductor materials gradually become popular

With the continuous development of technology, profound changes have taken place in the semiconductor diode industry, and new materials will become the new development focus of the industry. New material semiconductors represented by materials such as silicon carbide (SiC) and gallium nitride (GaN) have attracted industry attention due to their excellent performance such as wide band gap, high saturation drift speed, and high critical breakdown electric field. They are expected to become a new type of semiconductors. Wide bandgap semiconductor materials exhibit good material properties in practical applications. Due to technical limitations and high manufacturing costs, they are currently only appearing in high-end application scenarios. With the maturity of future technology, the manufacturing cost of wide-bandgap semiconductor materials will be further reduced, and will gradually become the mainstream product material in the semiconductor diode industry in the future.

2. Extend to higher value-added links

Scale advantage is an important means for companies in the semiconductor diode industry to control costs and improve their competitiveness. Therefore, low-end small and medium-sized enterprises that do not have scale advantages will find it difficult to continuously invest in R&D and market development, and it is difficult to survive in the industry. In recent years, China's semiconductor diode industry has increased its integration efforts, small companies have gradually withdrawn, and market concentration has gradually increased.

However, the process flow with high technical barriers and high product added value in the chip epitaxial link is in a disadvantageous position relative to the international leading level. The current market concentration of China's semiconductor diode industry is gradually increasing. With sufficient funds, companies have gradually increased their R&D investment. Especially in the SiC field, most large diode companies have capital arrangements. In addition, China's semiconductor diode packaging technology is at an internationally leading level, and the high standards of the packaging industry will in turn promote the accelerated development of the semiconductor diode chip industry, which in turn will drive the development of the entire industry and extend to higher value-added links.

1. Development status of China's semiconductor diode industry

According to the public data of the China Electronic Information Industry Statistical Yearbook, with the continuous development of China's semiconductor diode industry as a whole, the sales volume has increased from 285.6 billion in 2014 to 1,695 billion in 2018. Although from 2014 to 2016, due to the slowdown in the growth of the semiconductor market in mainland China, the substantial decline in the computer system industry, and the slowdown in the growth momentum of smartphones, the overall sales volume has declined. The overall market size of the semiconductor diode industry in China Maintain the upward growth trend. Especially in the past three years, the market expansion of emerging application fields such as the Internet of Things, cloud computing, big data, intelligent manufacturing, intelligent transportation, and medical electronics has prompted the rapid development trend of explosive growth in the market scale of China's semiconductor diode industry since 2017.

China is the world's largest semiconductor diode market, and there is a huge market demand for semiconductor diodes. Due to the performance of domestic products, most industries will not include domestic semiconductor diodes in the selection of raw materials. The "ZTE Incident" in 2018 accelerated the localization of semiconductor devices in various industries such as China's communications, automobiles, and electronics. After decades of technological research and development, the level of China's semiconductor diode manufacturing technology has stabilized, and some products have been exported on the basis of import substitution. In the context of the macroeconomic downturn in recent years, the export value of China's semiconductor diodes (except photodiodes or light-emitting diodes) from January to November 2020 was US$2.275 billion.

With the expansion of the market share of downstream industries in the industrial chain such as electronic complete machines and consumer electronic products, there is still considerable room for development in the semiconductor diode market. Huge market demand has prompted many R&D forces and funds to invest in this field. The fixed investment in China's semiconductor discrete device manufacturing industry has increased from 10.74 billion yuan in 2014 to 56.43 billion yuan in 2018, and semiconductor diodes accounted for the highest proportion of shipments. The market segment of the company has been favored by a large number of investors, and the capital boom has further promoted the rapid development of the industry.

2. Analysis of relevant policies in China's semiconductor diode industry

In recent years, the state’s support for the semiconductor industry has continued to increase. The government work report of the First Session of the 13th National People’s Congress will list “promoting the development of integrated circuits, fifth-generation mobile communications, aircraft engines, new energy vehicles, new materials and other industries”. In the first place in the development of the real economy, it highlights the important position of the semiconductor industry in the national strategy. In the future, the Ministry of Industry and Information Technology and related departments will continue to promote the development of industrial semiconductor materials, chips, devices and IGBT modules, and adjust and improve the policy implementation rules according to the industry development situation to better support the development of the industry. Intensify industrial chain cooperation through industry associations, in-depth promotion of industry-university-research collaboration, and promote the technological iteration and application promotion of China's industrial semiconductor materials, chips, devices and IGBT module industries.

1. Definition and classification of semiconductor diodes

A semiconductor diode is a unidirectional conductive two-terminal device made of semiconductor materials. It is widely used in rectification scenarios because of its characteristic that only allows current to flow in a single direction. It is one of the most commonly used electronic components. The semiconductor diode is one of the earliest discrete semiconductor devices. It can be connected to a variety of components such as resistors, capacitors, and inductors in a reasonable combination to form circuits with different functions. These circuits can achieve various functions such as rectification of alternating current, wave building, amplitude limiting, clamping, and voltage stabilization of the modulated signal.

According to specific uses, diodes can be divided into detection diodes, rectifier diodes, Zener diodes, switching diodes, isolation diodes, Schottky diodes, light emitting diodes, silicon power switching diodes, rotating diodes, etc. Among them, rectifier diodes, detector diodes, switching diodes, and Zener diodes are widely used.

2. Industry chain analysis of China's semiconductor diode industry

Participants in the upstream market of China's semiconductor diode industry chain include industrial silicon, packaging materials and other raw material suppliers and production equipment suppliers. The midstream of the industry chain is a Chinese semiconductor diode manufacturer. The downstream terminal application areas of the industry chain cover consumer electronics such as mobile phones, computers, and home appliances. And automobiles and other fields.
