Pusenmei Microelectronics Technology (Suzhou) Co., Ltd., operating under the brand PROSEMI, is a high-tech enterprise integrating R&D, production, and sales of electronic components. The company was founded in October 2019 by Zhenkun Tu. Its establishment followed years of steady growth in the electronic components industry, which began in 2012 with precursor companies, culminating in the integrated PROSEMI entity. In May 2024, the company secured tens of millions of RMB in an angel funding round led by Linxin Investment and Zhongke Chuangxing, with participation from Lingjun Capital. The core team includes professionals from prominent domestic and international firms such as Yageo, Ralec, Walter, AEM, and Littelfuse.
PROSEMI specializes in providing a diverse range of precision current sensing components and combined circuit protection solutions. Its product portfolio includes micro-resistance current detection resistors, fuses, discharge tubes, transient suppression diodes (TVS), electrostatic discharge (ESD) suppressors, and shunts. The company has broken through technical bottlenecks in product design, alloy materials, and manufacturing processes, enabling it to produce high-power alloy Current Sensing Resistors (CSR) and compete with international manufacturers from Germany, the US, and Japan. It is a notable manufacturer in mainland China with the capability to design, develop, and produce a full range of precision alloy current sense resistors.
The company operates on a B2B model, serving a wide array of industries including automotive electronics, new energy, industrial control, consumer electronics, smart homes, and communications. PROSEMI holds numerous certifications, such as IATF 16949, AEC-Q200, ISO9001, and ISO14001, along with over 200 patents. It maintains R&D centers and production bases in cities like Suzhou and Shenzhen to cater to a global client base.
