HUAYI.HUAYI was established in June 2017 as a high-tech enterprise under the Huatian Electronics Group, specializing in the R&D, design, packaging, testing, and sales of semiconductor power devices. The company's core competitiveness lies in its leading wafer design capabilities (particularly for 20V-150V medium-low voltage MOSFETs) and first-class packaging and testing processes. This has resulted in two major MOSFET series: Trench and SGT. With over 400 mass-produced products, they are widely used in electric vehicles, energy storage, 5G base stations, and other fields. Its packaging and testing product line covers over 60 package types, including TO-220 and TO-247, serving various power devices. The company has obtained multiple international management system certifications and holds over 76 intellectual property rights, committed to providing customers with highly reliable power semiconductor solutions.
