Changzhou Xinghai Electronics Co., Ltd. was established in November 1990. It is a company specializing in the production of various types of diodes. It has become one of the world-class diode production bases. The company's factory covers an area of ​​56,000 square meters and the plant area is 35,000 square meters. There are more than 1,200 employees, with a monthly output of about 880KK. It is expected that the total sales of diodes in 2012 will be about 10 billion, and the sales will reach 500 million yuan. The company has a modern office area of ​​5,000 square meters. And a laboratory that can carry out various reliability tests and inspections, with an area of ​​about 300 square meters and relatively complete supporting facilities. There are 53 scientific and technological personnel engaged in R&D, including 25 scientific and technological backbones, 60 quality management personnel, 3 senior experts, including 5 doctoral supervisors and professors who cooperate with the University of Electronic Science and Technology of China for research, 1 foreign expert, and a Xinghai Academician Workstation. In recent years, more than 30 new product and technological progress projects have been completed. 18 authorized patents have been obtained, including 3 invention patents.

The company has a complete range of products and specifications, including ordinary rectifiers (STD series), switches (DO-34, DO-35 packages), fast recovery (FR), high efficiency (HER, UF), ultra fast (SF), Schottky (SKY), bidirectional trigger tube (DB3), rectifier bridge (MBS, ABSBRIDGE), high reverse voltage (HV) and transient surge voltage absorption (TVS), voltage regulator (ZENER), bypass diodes (PV), constant current diodes (CRD), SOD123, SOD323, SMA, SMB, SMC, SOD123FL and other series and various packaging forms of diodes. All products comply with the EU RoHS standards.

The company has introduced a full set of advanced foreign equipment and scientific management systems, and its product quality enjoys a good reputation in the domestic and foreign markets. In recent years, the company has passed the ISO9002 international quality standard system, ISO9001:2008 quality management system, and ISO14001 environmental management system certification. In December 2008, it passed the ISO/TS16949:2002 certification. Since

its establishment and production in 1990, the company has long been trusted and supported by domestic and foreign customers and has achieved considerable development. We will adhere to the quality policy of "creating first-class quality and meeting customer needs" and wholeheartedly provide high-quality services to new and old customers.
