What Changzhou Galaxy Century Microelectronics does
Changzhou Galaxy Century Microelectronics (常州银河世纪微电子股份有限公司, ticker 688689.SH) is a Chinese Integrated Device Manufacturer (IDM) of semiconductor discrete devices, headquartered in Changzhou, Jiangsu Province. Founded in 2006 and publicly listed on the Shanghai Stock Exchange, the company designs, manufactures, and packages a comprehensive discrete semiconductor portfolio spanning diodes and rectifiers, ESD/TVS/Zener protection devices, bipolar transistors, MOSFETs (small signal, dual, medium/low voltage power, and super junction up to 1200V), analog and digital ICs (LDO, voltage regulators, voltage references), optocouplers, IGBT discretes and modules, SiC Schottky diodes and SiC MOSFETs, GaN HEMTs and Schottky barrier diodes, and integrated Intelligent Power Modules (IPMs) combining MOSFETs/IGBTs with gate drivers and protection circuits.
The company serves diverse end markets through an automotive-primary vertical segmentation: automotive electronics (NEV power electronics, BMS, motor drives, OBC, AEC-Q qualified SiC/IGBT devices), home appliances (compressor and motor control), AI/data centers (server power supplies, PFC, LLC converters), energy/power (PV inverters, energy storage BMS), industrial automation (servo drives, variable frequency drives), and computers/peripherals. Revenue is generated almost exclusively through B2B hardware sales via a global authorized distributor network supplemented by direct sales and application engineering for major accounts; pricing is quote-based and varies by product type, volume, and customer relationship.
Commercially, the company is executing a major capacity expansion (groundbreaking December 2025) targeting 5.5 billion automotive-grade discretes, 8 billion small signal/power devices, 2.5 billion optoelectronic devices, and 50 million IGBT/SiC power modules annually from a new Changzhou National High-Tech Zone industrialization base. Strategic emphasis is on wide-bandgap semiconductors (SiC, GaN) for NEV and renewable energy applications, supported by an R&D partnership with Fudan University on SiC MOSFET technology. The company participates in industry exhibitions (Electronica China 2026) and has received National Green Factory (2024) and Jiangsu Advanced Smart Factory (2025) designations from the Ministry of Industry and Information Technology. Reported revenue grew from $676M (2022) to $1,049M (2025), with 1,001–5,000 employees and an enterprise value of approximately $5.5B.
