What Are Diodes and How Do They Work?

Diode is a very simple, common and effective type of semiconductor device. As an introduction to diodes, it is very important that we understand what a “semiconductor” means. A semiconductor is in the middle of electrical conductivity. This means they are less conductive than conductors and more conductive than non-conductors. This is usually achieved by the level of impurities in them. A very common and useful strategy is to use it as part of the circuitry.

what do they do

The most common use of diodes is to convert alternating current (AC) to direct current (DC). Each diode is composed of a cathode and an anode, both of which are externally connected. When AC is applied, energy passes through the diode. In this situation, a positive voltage is applied to the anode and a negative voltage is applied to the cathode. If the polarity is reversed, the diode will stop current flowing, allowing current to flow in only one direction.

Types of diodes

· solid state – In the past, the tube diode was one of the most commonly used diode types in electronic devices. As technology has advanced, this older technology has been replaced by solid-state diodes. This type of diode is much smaller, more break resistant and longer lasting. Plus, they don’t generate as much heat as tubes and don’t require filament and filament power.

· LED – The type of diode that almost everyone has experienced, whether they know it or not, is the LED. LED stands for “Light Emitting Diode”. As with solid-state diodes, current can only pass through an LED when the polarity is correct. When current is passed through this unique type of diode, light is produced. Because these diodes are very small and require very little power to operate, LEDs are now found in almost all of our small to large electronics.

· tubes – Tube diodes are one of the first types of diodes used in our electronic devices. This type of diode consists of a vacuum tube containing a filament heater, as well as a separate power source for the filament. Some musicians prefer to play on amplifiers that use this type of diode, but it is not commonly found in today’s electronics.

· Feature – Due to their presence in almost all of our small to large electronic devices, semiconductor diodes come in all shapes and sizes. To solve the problems presented by special circuits, variations such as Schottky laser, infrared, tunnel, zener, varactor and others have been developed. Each is highly specific and designed for use only in specific devices.

Diodes come in a wide range of sizes, shapes, forms and functions. Due to their usefulness and versatility, they have become commonplace in almost every electronic device in our homes, businesses and elsewhere. They are absolutely essential to the technology we enjoy every day.
