GMSEMI
Diodes, MOSFETs, transistors, SiC/GaN and discrete power semiconductors
About the manufacturer
GMSEMI - Changzhou Galaxy Century Microelectronics - is an integrated device manufacturer focused on discrete and power semiconductor technologies. Its portfolio covers traditional silicon devices as well as newer wide-bandgap technologies, allowing the company to address rectification, protection and switching functions across a broad range of voltage and power levels.
The product range includes standard, fast and Schottky rectifiers, Zener, TVS and ESD protection devices, bipolar transistors, MOSFETs, IGBTs and selected SiC and GaN devices. The manufacturer also offers optoelectronic and integrated power solutions. This broad technology mix supports applications from low-voltage consumer electronics to higher-power converters and industrial energy systems.
Silicon, SiC and GaN devices provide different trade-offs in cost, conduction loss, switching speed, gate-drive requirements and thermal performance. Designers therefore need to select the device technology as part of the complete power-stage architecture rather than only by maximum voltage or current. Blocking voltage, RDS(on) or forward drop, switching charge, recovery behavior, junction-temperature limit and package thermal resistance are key parameters in power supplies, chargers, motor drives and energy-conversion equipment.
