ALL YOU NEED TO KNOW ABOUT DIOTEC DIODES

DIOTEC diodes for signal processing and rectifiers in power supplies, these components do a lot more than we think. Modern technology and electrical devices that we use today depend on many tiny electronic components. These components may be small, but some devices may not function optimally without them.

A particular example would be the simple yet robust DIOTEC diodes. You will probably be wondering, what is unique about these diodes? 

In this article, we will discuss all you need to know about DIOTEC diodes, why they are one of a kind, and how they can be applied.

What is a Diode and How Does it Work?

A diode is an electrical device that allows current as well as low and high resistance to pass through it. The diode, a two-terminal electronic component, conducts current in one direction but not the other.

In simpler words, diodes act as a unidirectional switch for current. Also known as rectifiers, this device can change alternating current (AC) into pulsating direct current (DC). 

Like most electronics components, diodes have anode and cathode, determining their polarity. For example, most diodes allow current when a positive voltage is added to the anode.

There are two sides to a diode, each side doped differently. The ‘P-side’ has a positive charge, while the ‘N-side’ has a negative charge. Both sides, when layered, form the ‘n-p junction’ at their meeting point.

Electrons can jump over the ‘n-p junction’ when a negative charge is applied to the n-side and a positive charge to the p-side. Although other diode technologies exist, the semiconductor diode is the most common kind in a circuit design.

Later in this article, we will explain diodes’ everyday applications and uses. For now, let’s discuss the types of diodes.

What are the Types of Diodes?

There are various types of diodes. Each of these diodes has individual functions and characteristics. Some are more similar than others in terms of applications and features.

Below are some common types of diodes you should know.

  • Zener Diodes

These diodes can conduct current either in the forward or reverse direction. A highly doped n-p junction makes it possible to allow current to flow in the reverse direction when the breakdown voltage is reached.

Zener diodes generate and regulate voltage, significantly stabilizing power supplies. They can also protect integrated circuits from voltage spikes.

  • Transient Voltage Suppressor (TVS)

This type of diode is specially designed to protect circuits from over-voltage. TVS diodes work by shunting excess current when the voltage exceeds the avalanche breakdown potential.

The exceptional ability to restrict voltage spikes over its breakdown voltage is why TVS diodes are called clamping devices. It can also be either unidirectional or bidirectional.

In addition, TVS diodes can be used in data and signal lines, AC power lines, telecommunication devices, MOS memory, and diversion in low-energy circuits.

  • Schottky Diodes

This type of diode is formed when a silicon semiconductor meets with a metal electrode. Schottky diodes are unipolar and have no depletion layer. 

Furthermore, these diodes have a fast-switching action with a low forward drop. Schottky diodes are perfect for preventing transistor saturation and can be used for over-voltage protection. They can also be used as low-loss rectifiers.

  • Other Types of Diodes
    • Avalanche Diodes
    • Constant-Current Diodes
    • Crystal Diodes
    • Gunn Diodes
    • Laser Diodes
    • Thermal Diodes
    • Light Emitting Diodes
    • Photo Diodes
    • PIN Diodes
    • Tunnel Diodes
    • Gold-doped Diodes
    • Super Barrier Diodes
    • Varicap Diodes

What are Diodes Used for?

Whether it’s Zener, TVS, or sm4001, all DIOTEC diodes have a common function of allowing electric current to pass in one direction. However, depending on the type of diode, there are specific ways it can be applied.

For instance, in 2020, scientists developed a Laser diode that emits the ‘world’s shortest lasing wavelength.’ This laser diode can treat skin conditions like psoriasis or gas and DNA analysis.

Although diodes are technically simple two-terminal semiconductor electronic components, they are essential to electronics and electrical applications. Here are some typical uses of diodes you should know.

  • LEDs

One of the most widely known uses of a diode is LEDs. Remember how some diodes allow current to pass only in a positive voltage? Light-emitting diodes, LEDs, are components that emit light when current passes through them.

LEDs use a unique type of doping that emits photons and creates light when an electron crosses the n-p junction. Depending on the doping type, any frequency of light can be cast, including infrared and ultraviolet light.

  • Conversion of Power

Diodes are primarily rectifiers – they can convert AC power to DC power. In addition, you can create several types of rectifier circuits with diodes.

An example of the power conversion function of a diode is extracting modulation from radio signals in radio receivers. Another typical use is in the laptop’s charge.

  • Circuit Protection

Diodes can be used as voltage protection devices. Electrical surges can damage sensitive electronic devices, and diodes are the perfect components for over-voltage protection.

In this function, diodes can short high-voltage spikes by diverting them to the ground to restrict them from ‘harming’ sensitive integrated circuits. Transient voltage suppressors are diodes designed for this function.

12 Devices That Use Diodes

Besides all the functions of diodes we mentioned earlier, these not-so-small-anymore electrical components have various applications in everyday living. Even the simplest devices apply diode technology in their design.

In truth, almost all electrical circuits require diodes. Here are some examples of devices that use diodes.

  1. Solar panels
  2. Flashlights
  3. Television system
  4. Laptops and Computers
  5. AM/FM Radios
  6. Mobile Phones
  7. Battery chargers
  8. Inverters
  9. LED bulbs
  10. Tube lights
  11. Laser printers
  12. Digital display boards
