In addition, Jiejie Microelectronics, Huawei Microelectronics, Xianke Electronics, and other well-known transistor manufacturers in China have performed well in their respective fields of focus.
How to choose a suitable manufacturer for 04
Faced with numerous transistor manufacturers, choosing a suitable supplier requires comprehensive consideration of multiple factors.
If it is an application with high reliability requirements such as automotive electronics and industrial control, international brands such as ON Semiconductor, STMicroelectronics, Infineon, etc. are usually a more reliable choice. These transistor manufacturers' products have undergone rigorous testing and meet automotive or industrial standards.
For cost sensitive applications such as consumer electronics and home appliances, high cost-effective products provided by domestic transistor manufacturers such as Yangjie Technology, Changjing Technology, and Guangzhou Feihong Semiconductor may be more suitable.
The mixed procurement strategy is also a common practice: international brand transistors are used for key parts, and domestic brand products are used for general circuits. This can ensure reliability and control costs.
It is worth noting that some international transistor manufacturers have production bases or cooperative factories in China, and leading transistor manufacturers in China are constantly improving product quality and entering the high-end market.
05 Selection and Supply Chain Suggestions
When cooperating with transistor manufacturers, small batch purchases can be made through authorized agents or distributors. There are many transistor manufacturers and supplier information on platforms such as Huaqiang Electronic Network.
For large-scale procurement, it is recommended to directly contact the transistor manufacturer or its branch in China to obtain more competitive prices and technical support.
Supply chain resilience is increasingly valued, and avoiding excessive reliance on a single transistor manufacturer has become an industry consensus. Diversified suppliers can reduce the risk of supply chain disruptions.
With the development of technology, third-generation semiconductors such as silicon carbide and gallium nitride are gradually becoming popular, and traditional transistor manufacturers are also laying out in these emerging fields. Paying attention to the technology roadmap of transistor manufacturers can help make more forward-looking choices.
A procurement manager from a Guangdong electronics manufacturing company found that replacing 30% of the transistors on the production line with domestic brands reduced annual procurement costs by 15%, while the product repair rate only increased by 0.2%.
With the launch of a new production line by a transistor manufacturer in Yangzhou, the market share of domestic brands in the automotive grade transistor market is expected to increase from the current 12% to 20% within two years. This competition about transistors has already surpassed individual components and become a microcosm of the global semiconductor industry chain restructuring.
