Featured Diodes


Diodes are discrete semiconductor devices that conduct electricity in a fixed direction, allowing current to flow in one direction while restricting current flowing from the opposite direction. They are typically rated by type, voltage, and current capacity. They are an active component, similar to transistors and ICs. 

From consumer electronics to communications, automotives to aerospace, diodes perform an array of critical functions. Boasting low power consumption, broad compatibility, a compact size, and a long operational lifespan, diodes are essential for:

  • Rectification
  • Voltage control
  • Radio wave detection
  • Current conversion 

Whether you need high speed switching or high voltage switching, DEX has the high power diodes you need in a variety of mounting styles and configurations, including modules, stud, and puck, and in packages as small as 0201 (0.6 mm x 0.3 mm) for applications with space limitations. Other packaging options range from MELF, axial, and radial leaded to 4-line ESD protection arrays in packages that protect up to 14 lines.

Leveraging a global database of thousands of suppliers, DEX boasts an available inventory of diodes including:

  • Bridge Rectifiers
  • Current Regulator Diodes
  • General Purpose, Power, Switching
  • PIN Diodes 
  • RF
  • Schottky Diodes & Rectifiers
  • Variable capacitance (varicaps, varactors)
  • Zener (arrays and single)

Top Industry Use Cases for Diodes

Diodes are essential components at every level in a broad range of industries, such as:

  • Industrial electronics, as infrared detectors, LEDs, and emitters
  • Defense and space industry, for low-voltage regulation and transient protection
  • Transportation technology, for LED and traffic signal technology
  • Telecommunications equipment, as limiters, gates, and clippers
  • Consumer electronics, as electronic lighting and status indicators
  • Computer and peripheral equipment, as logic gates and clampers
  • Medical and biotechnology, for laser monitoring and control, position sensing, and photon, electron, and x-ray measurement
