About DIODES INC /DEL/

Diodes Incorporated (ticker: DIOD) is a U.S.-based semiconductor company listed on the NASDAQ market in the United States. For French-speaking investors, it is best viewed as a diversified supplier of application-specific standard products rather than a pure-play designer of a single semiconductor niche. The company was founded in 1959 and has evolved into a global manufacturer and supplier of discrete, logic, analog, and mixed-signal devices. Its corporate headquarters is in Plano, Texas, reinforcing its U.S. base even though its operating footprint is highly international. ([sec.gov](https://www.sec.gov/Archives/edgar/data/29002/000095017025048864/2024_annual_report.pdf)) Diodes’ core business spans a broad portfolio of electronic components: diodes, rectifiers, transistors, MOSFETs, SiC diodes and MOSFETs, protection devices, logic devices, voltage translators, amplifiers, comparators, sensors, and power management products such as AC-DC converters, DC-DC switching solutions, linear regulators, voltage references, LED drivers, power switches, and voltage supervisors. The company also offers timing and connectivity solutions, including clock ICs, crystal oscillators, PCIe packet switches, multi-protocol switches, interface products, and high-speed signal integrity solutions. This breadth gives Diodes exposure to multiple end markets, including industrial, automotive, computing, communications, and consumer electronics. ([sec.gov](https://www.sec.gov/Archives/edgar/data/29002/000095017025048864/2024_annual_report.pdf)) From a competitive standpoint, Diodes positions itself as a global supplier of high-quality, application-specific standard products. Its business model benefits from scale, a wide product catalog, and a worldwide manufacturing and customer-support network. The company operates design, engineering, marketing, wafer fabrication, assembly/test, and sales/logistics capabilities across the United States, China, Taiwan, the United Kingdom, Germany, Japan, Singapore, South Korea, Italy, and other locations. That global footprint helps it serve OEM customers that value supply continuity, quality control, and responsiveness. Diodes also highlights internationally recognized manufacturing certifications, including ISO standards and IATF 16949 for automotive products. ([sec.gov](https://www.sec.gov/Archives/edgar/data/29002/000095017025048864/2024_annual_report.pdf)) Strategically, Diodes is aligned with secular growth areas such as automotive electrification and connected driving, cloud computing, AI servers, storage, data centers, edge AI, 5G networks, enterprise networking, and consumer IoT applications. This matters for investors because it gives the company exposure to long-term technology upgrades while still leaving it sensitive to the industry’s cyclical demand patterns. ([sec.gov](https://www.sec.gov/Archives/edgar/data/29002/000095017025048864/2024_annual_report.pdf)) Recent developments suggest improving operational momentum. In February 2026, Diodes reported fourth-quarter fiscal 2025 results and said full-year 2025 revenue increased 13% year over year, with fourth-quarter revenue at the high end of guidance. Throughout 2025, the company also introduced multiple automotive-oriented products, including buck converters, LED drivers, UART bridges, ideal diode controllers, and bipolar transistors aimed at 48V and other power-efficient automotive architectures. In October 2025, Diodes was recognized by Resilinc for supply chain excellence, underscoring the importance of resilience and transparency in a global semiconductor supply chain.
