Founded in 1995, JJW Electronic is a high-tech enterprise mainly engaged in the design, manufacturing, and marketing of semiconductor discrete components and power electronic devices. The company is located in Qidong Economic Development Zone, Jiangsu Province. It occupies a floor area of 83,958 square meters, including a clean workshop area of 27,907 square meters. With total assets of over 65 million USD and approximately 500 employees, of whom more than 12% are R&D engineers, the company has a strong R&D capability. It continuously invests about 4% of its sales revenue in R&D, ensuring independent development ability and owning intellectual property rights.

In 1995, the company produced and sold power devices such as transistors. In 2000, it began to build a power device chip production line, researching, developing, and mass-producing square-type single and bidirectional thyristor chips. In 2005, it established a power (electricity) packaging and testing production line, producing and selling JieJie brand power (electricity) plastic-sealed devices. In 2011, the company underwent a joint-stock reform and changed its name to "Jiangsu Jiejie Microelectronics Co., Ltd.". In 2017, it was listed on the Shenzhen Growth Enterprise Market with the stock code 300623. In recent years, the company has been committed to expanding the industrial chain and transforming and upgrading products, with projects such as the "High-end Power Semiconductor Industrialization Construction Project" of Jiejie Nantong Technology and the "Automotive-grade Industrialization Project of Power Semiconductors" of Jiejie Microelectronics.

The company's leading products include single and bidirectional thyristors, TVS, solid-state discharge tubes, low-junction capacitance discharge tubes, and other protective devices, high-voltage rectifier diodes, and power-type switching transistors. In addition, it also provides MOSFETs and IGBTs. For example, its MOSFET products have a VDS_Max range of -100V to 1000V and a VGS(th)_Typ of -2V to 3.5V. These products have their own structural characteristics and unique technologies, and are widely used in various electronic circuits.

JJW Electronic's products are applied in a wide range of fields. They are used in power adapters, battery chargers, and other aspects of consumer electronics to ensure efficient power conversion and stable operation. In the automotive field, the company's automotive-grade components can be used in vehicle lighting, infotainment systems, etc.. In addition, in the fields of industrial automation, renewable energy, and power supplies, the company's products also play important roles, such as being used in factory automation control systems and photovoltaic power generation systems to achieve power switching and regulation.

JJW Electronic is a high-tech enterprise in Jiangsu Province, an innovative enterprise in Jiangsu Province, a member unit of the China Semiconductor Industry Association, and an advanced member unit of the Power Electronics Branch of the China Electrical Equipment Industry Association. Since 2017, it has been listed among the top ten power semiconductor device enterprises in China selected by the China Semiconductor Industry Association. In 2023, it was selected as one of the top 100 industrial enterprises in Qidong City.

The company has an integrated business system for the R&D, design, production, and sales of power semiconductor chips and devices. Its main competitors are well-known international large-scale semiconductor companies. With the expansion of its sales scale, the company is in increasingly fierce market competition with international large-scale semiconductor companies, which also promotes the company to continuously improve its technological level and product competitiveness.

In conclusion, JJW Electronic has a certain influence in the semiconductor field with its continuous R&D investment, rich product line, and wide range of applications, and is committed to contributing to the development of the global semiconductor industry.
