A diode is a type of electrical component used to direct current in one direction only. The EGP20G-E3/73 is an example of a single rectifier diode, commonly used in a variety of applications. This article will explore the application field and working principle of the EGP20G-E3/73.

What is a Single Rectifier Diode?

A single rectifier diode is an electrical component with a positive and a negative end. It allows current to flow in one direction only and blocks current in the opposite direction. This makes it possible to convert alternating current (AC) to direct current (DC). It is also commonly used to limit the amount and/or direction of current flow, providing protection in electrical and electronic systems.

Application Field

The EGP20G-E3/73 is a general-purpose single rectifier diode, with a small size and low-cost. Its low voltage drop makes it ideal for AC-to-DC rectification applications in a variety of fields, such as:

• Power supplies
• Switch-mode power supplies
• DC output rectifier
• Battery charge and discharge control
• Automotive
• LED lighting

Working Principle

The EGP20G-E3/73 works on the principle of PN junction depletion. A PN junction is formed when two types of semiconductor materials are connected together. A depletion region is formed within the junction, which blocks current in both directions. When a voltage is applied to the junction, the depletion region changes and the current begins to flow in one direction only. The diode is said to become “forward-biased”, the current flows in the direction of the forward bias, and it becomes “reverse-biased”, when the current flows in the opposite direction to the bias. With single rectifier diodes, like the EGP20G-E3/73, when the forward bias is applied, or current is flowing in the correct direction, it will allow the current to pass. In contrast, when the bias is reversed, or current is flowing in the wrong direction, the diode blocks the current.

Conclusion

The EGP20G-E3/73 is a single rectifier diode, used in a variety of applications, including power supplies, switch-mode power supplies, DC output rectifier and battery charge and discharge control. It works on the principle of PN junction depletion, allowing current to flow in one direction, and blocking current in the opposite direction.
