What is a Diode?

A diode is an electronic component with two terminals and an asymmetric transfer characteristic. It has a low resistance to current flow in one direction and a high resistance to current flow in the other direction. A semiconductor diode is a crystalline piece of semiconductor material containing a p-n junction that is connected to two electrical terminals. Diodes allow an electric current to pass in the forward direction, while blocking electric current in the reverse direction. This unidirectional behaviour is called rectification and is used in order to convert AC current to DC current. Semiconductor diodes begin conducting electricity when a certain threshold voltage is applied in the forward direction.

Types of Diodes

There are several different kinds of diodes at Future Electronics. We stock many of the most common types categorized by several parameters including maximum reverse recovery time, maximum reverse current, maximum average rectified current, forward voltage, maximum reverse voltage, power dissipation, maximum average forward current, maximum peak current and packaging type, among others. Our parametric filters will allow you to refine your search results according to the required specifications.

Diodes from Future Electronics

Future Electronics has a wide range of programmable diodes from several manufacturers. Once you decide if you need Bridge Rectifiers, Current Limiting Diodes, Fast Rectifiers, Schottky Diodes, Schottky Rectifiers, Small Signal Diodes, Standard Rectifiers, Switching Diodes, Tuning / Varactor Diodes, Ultrafast Rectifiers or Zener Diodes, you will be able to choose from their technical attributes and your search results will be narrowed to match your specific diode application needs.

Applications for Diodes:

The nonlinear current–voltage characteristic of semiconductor diodes can be modified by varying and modifying the semiconductor materials. Zener diodes are used to regulate voltage. Tuning / varactor diodes are used to electronically tune radio and TV receivers. Other diodes can be used to protect circuits from high voltage surges, generate radio frequency oscillations or produce light. Diodes can be found in a wide range of applications including radio demodulation, power conversion, logic gates, ionizing radiation detectors, temperature measurement and current steering.
