What Excelliance MOS does

Excelliance MOS Corporation (杰力科技), founded in 2008 and headquartered in Zhubei City, Hsinchu County, Taiwan, is a power device and IC design company specializing in power semiconductor process development. The company is publicly listed on Taiwan's TPEx/GTSM (OTC) market under code 3533 and employs 51-100 people across offices in Hsinchu, New Taipei City, and Shenzhen (via subsidiary 深圳杰致科技有限公司).

Its core product portfolio covers Middle Voltage MOSFETs (40V-399V), Low Voltage MOSFETs (20V-30V), AC/DC Controllers, and DC/DC Power ICs including Buck Converters, Buck Controllers, Power Switches, Linear Regulators, and integrated Power Management ICs (PMICs), as well as GaN HEMT devices for high-efficiency applications. The technology base rests on trench MOSFET, split-gate, common-drain, and GaN HEMT process architectures, protected by a granted patent portfolio across Taiwan, China, and the United States. The company describes itself as one of the few IC design firms with vertical integration capability, combining in-house and supplier technology to deliver complete power solutions.

Excelliance MOS sells directly to electronics manufacturers — primarily notebook, desktop motherboard, VGA card, power supply, LCD monitor/TV, smart home, power tool, and battery management system ODM/OEMs — through a sales-led motion. Named key customers include Wistron (Excellence Partner Award, 2023) and Compal Electronics (Net Zero Supply Chain Declaration participant, 2023). Revenue is generated from hardware sales of power devices, PMICs, and integrated power modules on a quote-based B2B pricing model that is not publicly disclosed. The company also holds ISO 14064-1 organizational GHG verification and ISO 14067 product carbon footprint certification, signaling a deliberate ESG positioning around its corporate and product-level environmental footprint.
