Thyristors - SCRs

Thyristors are a family of electronic components that are used to control electrical currents and voltages. They are also sometimes referred to as silicon-controlled rectifiers (SCRs). The JAN2N2328AS is a type of SCR that is widely used in many applications, such as switching power supplies, motor control, lighting control, and voltage regulation systems.

Anatomy of a SCR

An SCR (JAN2N2328AS) consists of two semiconductor layers that are connected to two P and N terminals. One of the layers is called the anode and the other is called the cathode. The P and N terminals are used to control the flow of current through the SCR. The structure of a SCR is shown in Figure 1.

Working Principle

An SCR (JAN2N2328AS) is a unidirectional device, meaning it allows current to flow in one direction only. This is called forward mode operation and is initiated when the P and N terminals are connected to a positive DC voltage. When the positive voltage is applied to the P terminal, it will create a small leakage current that passes through the device and activates it. Once the SCR has been activated, it allows the full current to flow through it until the voltage is removed or interrupted.For example, if the SCR (JAN2N2328AS) is used in a power supply, the switching of the load will be achieved by activating and deactivating the SCR. The load will be allowed to flow in the forward direction when the SCR is activated and will be blocked when the SCR is deactivated. This means that the power supply can be switched on and off as needed and can regulate the currents and voltages as desired.

Application Fields

The JAN2N2328AS is a versatile SCR that is used in a wide range of applications. It is commonly used in power supplies and motor control systems, such as elevators, fans, and automatic sliding doors. It is also popular in lighting control systems for dimmer fans and LED lighting systems, as well as for voltage regulation in automotive applications. The SCR is also widely used in AC line protection circuits and UPS systems. This type of circuit will detect when there is an abnormally high line voltage, and the SCR will be used to switch off the power supply in order to prevent the system from being damaged.In addition, the JAN2N2328AS can be used in other applications such as motor overload protection, overcurrent protection, voltage overload protection, arcing suppression, and flying capacitor circuits. These types of circuits are used to control and protect electrical systems, ensuring that they run safely and efficiently.

Conclusion

The JAN2N2328AS is a type of silicon-controlled rectifier that is commonly used in many applications, such as power supplies, motor control, and lighting control systems. It is a versatile device that can be used to control currents and voltages, switch the power supply on and off as needed, and protect electrical systems from damage. This makes it a reliable and essential component for any system.
