Diodes Incorporated
Diodes Incorporated (DIOD) is a publicly traded U.S. company (Nasdaq: DIOD) that has transformed from a distributor into a leading global manufacturer of discrete, logic, analog, and mixed-signal semiconductors. Headquartered in Plano, Texas, it serves global markets such as automotive, industrial, computing, consumer electronics, and communications.

The company was founded in 1959, initially operating as a regional semiconductor trading company named David Lloyd. A pivotal turning point came in 1990 when Taiwan's Silitek Corporation (Lite-On Group) acquired a 46% stake, becoming the majority shareholder. This investment provided crucial capital and strategic direction, driving the company's transformation from a trading model into a vertically integrated semiconductor firm encompassing design, manufacturing, and sales.

The company's growth is closely tied to an aggressive acquisition strategy. Since the early 2000s, a series of acquisitions have significantly expanded its product portfolio and manufacturing capabilities.

  Year Acquired Company Major Gain
  2008 Zetex Semiconductors  Enhanced analog and power product lines
  2015 Pericom Semiconductor  Gained high-speed connectivity and signal integrity technology
  2020 Lite-On Semiconductor  Expanded product portfolio and packaging capabilities
  2022 onsemi， the South Portland wafer fabrication facility  Significantly boosted in-house wafer fabrication capacity


Through these acquisitions, the company evolved from a discrete-focused player into a comprehensive supplier offering complete solutions in "Discrete Components + Power Management + Interface Connectivity", while strengthening its IDM (Integrated Device Manufacturer) model. Financially, the company has shown consistent growth, with 2024 revenue reaching $1.31 billion and revenue in 2025 continuing to achieve year-over-year growth.
