Patent technology: We have core patents such as "multi chip protection diode", and our products cover automotive grade standards.
2. Changjing Technology
Development speed: A cutting-edge enterprise established in 2018, rapidly expanding its range of diodes from consumer grade to automotive grade MOSFET。
Advantage: One stop procurement service, suitable for industrial and consumer electronics needs.
3. Huawei Microelectronics
Historical accumulation: Established in 1965 and launched in 2001, focusing on power semiconductor devices.
Technical contribution: Leading the national standard GB/T 35010.32018, with patents covering low capacitance power transistors, etc.
4. Jiejie Microelectronics
Segmented leader: thyristor IDM manufacturer (launched in 2017), expanding to TVS protection devices and high-voltage rectifier diodes.
Application scenarios: Power electronics and industrial power protection.
5. Solid Technetium Electron (GOODARK)
Product breadth: The most comprehensive diode manufacturer in China, with over 50 series and 1500 varieties, covering military, photovoltaic and other fields.
Technical strength: Mastering patents such as "bidirectional transient suppression device", with an accuracy of ± 1% for glass sealed voltage regulators.
3、 Market Pattern and Emerging Forces
Global market share: In the glass sealed voltage regulator market, Tongke Electronics (18.56%) and Ansenmei (16.5%) occupy the top two positions, and the Chinese consumer market accounts for over 70% of the global market.
Localization trend: Companies such as Bern Semiconductor are accelerating their layout and enhancing their domestic substitution capabilities through the entire wafer manufacturing chain (such as Tianjin and Henan bases).
Growth areas: Automotive electronics and green energy (such as solid technetium photovoltaic diode modules) have become the focus of technological competition.
summarize
Choosing a brand of voltage regulator diode should be based on the scenario:
High end/Automotive Electronics: Priority given to ON Semiconductor, Toshiba, and ROHM;
Industrial/consumer electronics: DIODES, Yangjie, and Changjing offer better cost-effectiveness;
Customization/Special Environment: Gude and Huawei's wide voltage range (2.4V-200V) and military grade products are advantageous directions.
The global market is expected to reach $348 million by 2030 (CAGR 6.33%), and Chinese brands are gradually rewriting the competitive landscape dominated by Europe and America through technological upgrades and capacity expansion.
