Thyristors, also known as silicon-controlled rectifiers (SCRs), are accessible and relatively inexpensive components which can be used in a variety of applications. The 2N6397TG, for example, is a thyristor which can be used to switch and control electrical power, especially in power supply systems. In this article, we will describe the application field and working principle of 2N6397TG thyristor.

Applications

2N6397TG thyristors are designed to control the switching of high amounts of power under various conditions. They are mainly used in high voltage power blocks, motor drive power supplies, and uninterruptible power supplies. In addition, the 2N6397TG is suitable for use in lighting fixtures and controllers, HVAC systems, microwave ovens, and electronic systems, amongst other industrial and commercial applications.

The various characteristics and parameters of the 2N6397TG make it suitable for a broad range of applications. It is designed with a breakdown voltage of 600 volts, a maximum on-state current of 20A and a maximum gate trigger current of 3.0A, making it compatible with a wide range of power sources. Additionally, the anode-cathode voltage and current ratings are high and remain consistent even after prolonged use, which makes the 2N6397TG suitable for systems that require reliable and long-life operation.

Working Principle

The 2N6397TG thyristor works on the principle of a two-terminal semiconductor diode, capable of alternating between an on state and an off state. When a small current is applied to the gate terminal, the 2N6397TG enters its ‘on’ state and conducts current, allowing the flow of current through the anode (A) and cathode (K) terminals. Applying a negative voltage to the gate terminal, on the other hand, will cause the thyristor to return to its off state and disconnect the anode and cathode. This can be used to regulate the flow of current and control various applications.

A thyristor can also be used to produce a steady waveform from a somewhat irregular input waveform. This is done by applying a steadily increasing reference voltage to the gate terminal. When the output waveform matches the reference waveform, the gate terminal will be cut off and the waveform held steady. In addition, if the output waveform begins to drop, a corresponding decrease in the reference voltage will cause the 2N6397TG to abruptly shift from the on state to the off state, holding the waveform steady.

Conclusion

The 2N6397TG is an excellent choice for controlling high amounts of power in various applications. Its easy-to-use setup and consistent performance make it an ideal choice for industrial, commercial and even residential applications. By comparing the characteristics and parameters of the 2N6397TG before it is put into use, engineers and system designers can be sure they are receiving a reliable, cost-effective solution that will provide long-term power control.
