About Alpha and Omega Semiconductor Limited

Alpha and Omega Semiconductor Limited (AOSL) is a global enterprise that designs, develops, and supplies crucial power semiconductor solutions for a wide range of applications, including computing, consumer electronics, communication, and industrial sectors. The company operates internationally, serving markets in Hong Kong, China, South Korea, and the United States. Among its core offerings are power discrete components, such as various types of MOSFETs (e.g., metal-oxide-semiconductor field-effect transistors, SRFETs, XSFET, and high-voltage variants, including ESD-protected models) and insulated gate bipolar transistors (IGBTs). These components are integral to a vast array of devices, spanning consumer electronics like smartphones, laptops, TVs, and gaming consoles; computing infrastructure including desktops, servers, and data centers; communication equipment such as base stations; and diverse industrial applications like motor control, power tools, electric vehicles, white goods, UPS systems, solar inverters, and industrial welding. AOSL also provides power integrated circuits (ICs), which are designed to efficiently manage and regulate power within electronic systems. These ICs are critical for controlling voltage levels and current flow, finding applications in everything from flat-panel displays, notebooks, and graphics cards to servers, DVD/Blu-Ray players, set-top boxes, and networking hardware. The product portfolio further extends to specialized components like aMOS5 MOSFETs, optimized for high-demand applications such as fast chargers, AC adapters, PC power supplies, servers, industrial power, telecom, and data centers. Additionally, it supplies Transient Voltage Suppressors (TVS) for safeguarding electronic devices like laptops and televisions against power surges. Other innovative solutions include EZBuck regulators, SOA MOSFETs for hot-swappable systems, RigidCSP for advanced battery management, and Type-C power delivery protection switches. Established in 2000, the company maintains its headquarters in Sunnyvale, California.
