Thyristors are an important category of electronics components, and within them is a subgroup known as silicon controlled rectifiers (SCRs). The TN1605H-6G belongs to this group of devices and has a variety of applications. This article will explain the working principle and discuss some of the ways the TN1605H-6G is used.

What is a Thyristor?

Thyristors are three-terminal semiconductor devices with a low-voltage and high-current capacity. They are most commonly used in power electronics applications as they are capable of withstanding large voltages and currents. A thyristor acts as a switch that is only activated when a current passes through the gate terminal. Once the current is removed, the thyristor turns off and current ceases to flow.

What is a SCR?

A silicon controlled rectifier (SCR) is a type of thyristor. It consists of four layers of semiconductor material, hence why it is often referred to as a four-layer device. The layers are arranged such that when a certain voltage is applied to the gate terminal, a current can flow between the anode and cathode terminals. This current is known as the forward conduction current. The reverse conduction current is the current that flows when the thyristor is off and a negative voltage is applied to the gate terminal.

TN1605H-6G Application Fields

The TN1605H-6G, also known as an SCR or silicon controlled rectifier, is mainly used in industry and commercial applications as a power switching component, such as in power supplies, electric motors, and light dimmers. It is also used in electric ovens and stoves, toasters, hair dryers, heaters, electric ovens, and other motor-driven applications. The TN1605H-6G is also suitable for use in electric shock and over-current protection, power factor correction, and electric arc detection.

TN1605H-6G Working Principle

The TN1605H-6G has two major terminals: the anode (positive) and the cathode (negative). The SCR is normally off until a voltage is applied to the gate terminal. When the gate terminal is connected to a positive voltage, it acts as an ON/OFF switch, allowing current to flow from the anode to the cathode in the forward conduction direction. The current can be controlled and switched on and off very quickly, making it an ideal choice for power switching applications.

When a voltage is applied to the gate terminal, the gate current turns the thyristor on and a forward current starts to flow from the anode to the cathode. When the current reaches certain levels, the SCR turns off by itself, and the reverse conduction current stops the flow of current from the gate terminal. If a negative voltage is applied to the gate terminal, the SCR turns off and the reverse conduction current stops the flow of current from the gate terminal.

Conclusion

The TN1605H-6G is a type of Silicon Controlled Rectifier (SCR) which is suitable for power switching applications. Its working principle involves the application of a voltage to the gate terminal to turn the SCR on and allow current to flow through the anode and cathode terminals, and then it turns off again when the current reaches certain levels. It is widely used in industry, commercial and domestic applications for power control, electric shock and over-current protection, power factor correction, and electric arc detection.
