Overview
Diodes Incorporated is a United States semiconductor manufacturer and supplier focused on application-specific standard products. The company serves the analog, discrete, power, logic, and mixed-signal semiconductor markets, selling components used by equipment manufacturers and electronic-system designers around the world. Its headquarters are in Plano, Texas, and its products support consumer electronics, computing, communications, industrial equipment, and automotive applications. The company's portfolio spans both foundational semiconductor components and more specialized integrated solutions. Discrete products include diodes, rectifiers, transistors, MOSFETs, and protection devices. Its analog and mixed-signal offerings include amplifiers, comparators, Hall-effect sensors, temperature sensors, isolation products, voltage references, and functional-specific arrays. Diodes also supplies power-management devices such as LED drivers, AC-to-DC converters and controllers, DC-to-DC switching and linear regulators, USB power switches, load switches, voltage supervisors, and motor controllers. Additional product families address timing, connectivity, switching, and signal integrity for high-speed data paths. Diodes positions these products as practical building blocks for end-user equipment rather than as consumer-facing products. Applications identified for the company include satellite television set-top boxes, portable media devices, datacom equipment, ADSL modems, power supplies, medical equipment that is not life-support equipment, personal computers and notebooks, flat-panel displays, digital cameras, mobile handsets, wireless LAN access points, brushless DC motor fans, and automotive systems. The breadth of these applications reflects a business model based on supplying many customers across several electronics sectors, with products integrated into larger systems under other brands. A significant part of Diodes' expansion has come through acquisitions and manufacturing-capacity investments. The company acquired Zetex Semiconductors in 2008, Power Analog Microelectronics in 2012, Pericom Semiconductor in 2015, Texas Instruments' Greenock wafer fabrication plant in 2019, and Lite-On Semiconductor in 2020. In June 2022, it completed the acquisition of a wafer-fabrication facility in South Portland, Maine, from onsemi, together with the transfer of the facility's employees. These transactions broadened Diodes' product capabilities, strengthened its manufacturing footprint, or added technologies and customer relationships in adjacent semiconductor categories. In January 2024, Diodes announced three dual-channel power switches, extending its power-management portfolio. In the fourth quarter of 2024, it completed the acquisition of Fortemedia, a company associated with voice and audio signal-processing technologies. Leadership succession also became a prominent element of the company's recent strategy: Gary Yu was named president effective January 2, 2024, while Keh-Shew Lu continued as chairman and chief executive officer for a transition period. Diodes subsequently announced that Yu would become chief executive officer effective May 14, 2025, with Lu continuing as chairman of the board. Diodes is therefore best understood as a business-to-business semiconductor platform combining discrete components, power management, analog and mixed-signal products, and selected connectivity and signal-processing technologies. Its competitive proposition rests on product breadth, application support, manufacturing scale, and the ability to serve multiple equipment markets rather than on a single consumer product line.
History
Diodes Incorporated is a semiconductor company whose business is centered on application-specific standard products for electronic equipment manufacturers. Its portfolio covers discrete, analog, power, logic, and mixed-signal components, allowing it to participate in several stages of an electronic system's power, control, protection, sensing, timing, and connectivity functions. Rather than selling finished consumer devices, the company supplies components that are incorporated into products made by other manufacturers. The company developed a broad market scope across consumer electronics, computing, communications, industrial equipment, and automotive systems. Its products have been used in equipment ranging from satellite television set-top boxes, portable media devices, datacom products, and ADSL modems to power supplies, personal computers, notebooks, displays, cameras, mobile handsets, wireless LAN access points, medical equipment, and brushless DC motor fans. Automotive applications became another important area of relevance as electronic content expanded in vehicles. Diodes' growth has been supported by acquisitions that added products, engineering capabilities, manufacturing assets, and customer access. Zetex Semiconductors was acquired in 2008. Power Analog Microelectronics was acquired in 2012, adding power-related analog capabilities. In 2015, Diodes acquired Pericom Semiconductor, strengthening its portfolio in connectivity, signal integrity, timing, and related interface technologies. In 2019, it acquired Texas Instruments' Greenock wafer-fabrication plant, expanding internal manufacturing capacity. In 2020, it acquired Lite-On Semiconductor, broadening its semiconductor product and customer base. Manufacturing expansion continued with the South Portland wafer-fabrication facility. On June 3, 2022, Diodes completed the acquisition of the facility and its operations from onsemi, referred to as SPFAB, and also transferred the employees working there. The transaction gave Diodes an additional manufacturing asset and reinforced its strategy of combining product expansion with control over selected wafer-production capabilities. The company continued to develop its power-management range in 2024, when it announced three dual-channel power switches. It also completed the acquisition of Fortemedia during the fourth quarter of 2024. The Fortemedia transaction added audio and voice signal-processing capabilities to a company historically identified primarily with discrete, analog, power, and mixed-signal semiconductor products. Leadership succession was another important recent development. On December 26, 2023, Diodes announced that Gary Yu would become president on January 2, 2024. Keh-Shew Lu remained chairman and CEO during the planned transition, with the announcement indicating that he would continue as CEO at least through May 31, 2027. Diodes later announced that Yu would become CEO on May 14, 2025, while Lu would continue as chairman of the board. Today, Diodes operates as a global business-to-business semiconductor supplier. Its identity is defined by breadth of standard and application-oriented components, diversified end markets, acquisition-led portfolio development, and a manufacturing network intended to support dependable supply. The company remains active, with its products positioned as enabling components for power conversion, signal control, protection, sensing, connectivity, and other functions in electronic systems.
