B2100BE-13 Application Field and Working Principle

Diodes are solid-state electronic devices used in electrical circuits as a bridge between two nodes. They usually act as a one-way valve that only allows current to flow in one direction, while preventing current from flowing in the opposite direction. They also act as a gate that can turn off the current altogether, preventing it from flowing in any direction. The B2100BE-13 is a single-polarity, high-voltage, rectifier diode that is commonly used in a variety of electronic applications.

Application of the B2100BE-13

The B2100BE-13 is a Do-214AB package, with a reverse voltage of 400V and a peak repetitive reverse voltage of 800V. This diode is typically used in a variety of AC-DC, DC-DC, and high-speed switching applications. These applications are generally in electronics that require high voltage protection, including LED TV power supplies and computer power supplies, as well as automotive, power, and telecommunications applications. The high speed switching nature of this diode makes it a suitable choice for applications that require switching between positive and negative polarities with fast response rates.

Working Principle

The most basic operation of a diode is that it functions as an electrical one-way valve, allowing current to flow in one direction while preventing it from flowing in the opposite direction. This simple operation is known as rectification and can be thought of as a semiconductor version of an on-off switch. Rectification is achieved through the unique molecular structure of diodes, which are built from semiconductor material such as silicon. One end of the diode is made from P-type semiconductor material, which contains an excess of positive charges and a deficiency of electrons. The other end is made from N-type semiconductor material, which has an excess of electrons and a deficiency of positive charges.

The P-type end is the anode and the N-type end is the cathode, and when voltage is applied, current can flow through the diode from the anode to the cathode. However, when the voltage is reversed, the current flow is prevented, as the P-type material offers a barrier against the flow of electrons. This is the basic working principle of a diode and is repeated in the operation of the B2100BE-13.

Conclusion

The B2100BE-13 is a rectifier diode that is widely used in various AC-DC, DC-DC, and high-speed switching applications. It is composed of a P-type and N-type semiconductor material that acts as a one-way valve for electrical current, allowing it to flow one way, and preventing it from flowing in the opposite direction. Therefore, it is classified as a single-polarity, high-voltage, rectifier diode.
