Thyristors - SCRs

SCRs, or silicon controlled rectifiers, are a type of thyristor, which is a form of electronic voltage and current switching device. They are most commonly used to maintain, control and switch electric power in a variety of applications, including motor controls, power supplies, lighting controls and communications systems. The VS-2N684 is a type of SCR, and it can be used in a number of different applications.

Application Field of VS-2N684

The VS-2N684 is particularly suited for applications that require a reliable and efficient control of electrical energy. It can be used in electric motor controls, such as starters, electric inverters, converters and drivers. It is also suitable for the regulation and control of AC and DC electric power in power supplies and industrial equipment, such as power transformers, electrical transformers and equipment used in factory automation. In addition, the VS-2N684 can be used in lighting control systems, such as dimmers, halos and floodlights, as well as in communications systems, such as switching lines, analog-to-digital converters and communication interface circuits.

Working Principle of VS-2N684

The VS-2N684 works on the principle of two-way conduction. This means that current flows in two directions through the thyristor when it is in its “ON” state. When the voltage applied to its “gate” is greater than a certain level, the SCR is triggered and the current flowing through it starts to increase. This increase in current is known as “forward conduction”. As the current continues to increase, the forward conduction can reach its peak, known as the “holding current”, or the “saturation current”. At this point, the SCR is in its “saturated” state and the voltage across it is very small.

When the voltage applied to the gate is reduced to a certain level, the SCR will turn off and the current flowing through it will be reduced. This is known as “reverse conduction”. The reverse conduction can reduce the current flowing through the SCR to zero. In this state, the VS-2N684 is in its “off” state and the voltage across it is very large.

The VS-2N684 is a versatile SCR device that can be used in many different applications. It is highly reliable and efficient, and it is able to control the electrical energy in a variety of ways. The two-way conduction principle of the VS-2N684 makes it an ideal choice for a wide range of applications where reliable and efficient power control and switching is required.
