Diode is the important electronic components works as two-terminal unilateral semiconductor device that allows current to flow merely in one direction. Manufactured by three semiconductor material silicon, selenium, and germanium, this device blocks the current flowing in reverse direction. Anode and cathode are the two terminals of a diode. This widely used electronic component is not only utilized as rectifiers but its functionality and applications are defined according to their types. It is forward biased if current is allowed otherwise it is reverse biased.

Consider the best type before purchasing

Different types of diodes are available to be used in electronics design to perform different functions according to their individual properties. As each diode has own characteristics thus before you Buy Diode and include into the function, it is essential to first consider its types, method of operation, structure, how to use, and relevant information. Some of the common types of diode mentioned below with some useful details.

1. Tunnel

It is a two terminal electronic device used as high speed switch for microwave applications because of the tunnel effect that provides very speedy operation in microwave frequency region. Although, these are not extremely used today but known for the great performance that exceeds that of various devices.

2. Zener

This is very useful and special type of diode used in extreme quantities as a voltage regulator. It gives the stable reference voltage. It runs under reverse bias conditions and breaks down the voltage when it is reached. If the current through a resistor is limited, it produces the stable voltage.

3. Varactor or Varicap

Acts like a variable capacitor, these diodes perform usually at reverse bias state. It is such kind of diode whose junction capacitance can be changed with an applied reverse voltage i.e. width of junction increases as applied reverse voltage increases that ultimately decreases the capacitance. Frequency multipliers, voltage-controlled capacitors, parametric amplifiers, voltage controlled oscillators, FM transmitters as well as phase locked loops in TV sets, cellular telephone, and radio are main applications of varactor diode.

4. Light emitting (LED)

LEDs are one of the widely known and a used type of diodes which produces light when receives the accurate forward current flowing through it. These kinds of diodes are available in stock of colors and varieties. There are infrared light emitting diodes that produce infrared light to be used extensively in remote controls and there are some LEDs also where light cannot be seen because they are at the frequencies which don’t allow visibility.

5. Laser

These are different from that to LEDs because it produces coherent light and are more expensive. Laser diode has limited life and emit narrow wavelength spectrum. Having very quick response times when compared to LED, these diodes are used in laser fax machines, CD players, high-performance imagers, laser printers, CD-ROM drives, bar code scanners, and various optical storage devices.

Why purchase diode online?

The best way to get the required high-quality diode designed by the leading manufacturers of the industry is to go for Diode Online Purchase. This is the easiest and convenient way to buy the premium device at reasonable price by comparing the various options available. There are many website where you can compare several products on the basis of given details and buy the superior one.
