Diodes

Diodes

What are Diodes?

A diode is a semiconductor device that acts as a one-way switch for current, allowing current to flow easily in one direction while restricting it in the opposite. Diodes have numerous applications, including in rectifiers to convert alternating current (AC) to direct current (DC), demodulation in radio receivers, and as components in logic circuits or temperature sensors.

Express Electronics has 10,000 products in stock and access to hundreds of thousands more, so we can find the diode you need no matter how specialised the purpose. Call us on 01904 656 923 or contact us.

Diode - Electronic Component

Types of Diodes

Express Electronics have 10,000 products in stock and access to hundreds of thousands more, so we can find the diode you need no matter how specialised the purpose.

  • Rectifier Diode: Converts alternating current into direct current by allowing current to flow in only one direction. It is commonly used in power supplies to provide a stable DC voltage from an AC source.
  • Zener Diode: Allows current to flow in both the forward and reverse directions when a specific reverse voltage is reached. It is commonly used for voltage regulation and protection in electronic circuits.
  • Light emitting Diode: Emits light when an electric current passes through it. LEDS are widely used in displays, indicators and lighting due to their energy efficiency and long lifespan.
  • Schottky Diode: Known for its low forward voltage drop and fast switching speed, achieved through the function of a metal with a semiconductor. Commonly used in high-frequency and high-efficiency applications such as power rectification and RF circuits.
