Thyristors are semiconductor devices that are made of four layers of alternating P-type and N-type semiconductor materials. A Thyristor usually consists of a gate, a control electrode, an anode and a cathode. Thyristors are known as switched-mode power supplies, Static Relay and Automatic-Resetting Circuit Breakers because of their ability to be switched on and off using the gate signal.

The 2N1806 is a Thyristor — more specifically, a Silicon Controlled Rectifier (SCR) — that is capable of blocking voltages up to 600V as well as carrying currents up to 36A. This enables it to be used in a variety of different applications such as Power Supplies, Switch-Mode Power Supplies, Motor Control, AC Voltage Controllers, and industrial Automation.The most common application for the 2N1806 is for controlling the voltage and current in a power supply. It can be used to switch on and off loads or to regulate the voltage and current levels.

The working principle of the 2N1806 is based on its ability to be switched on and off by the gate signal. When the gate voltage is low (below the threshold gate voltage), the gate of the SCR does not open, so the SCR does not conduct current. However, when the gate voltage is increased above the threshold level, the gate of the SCR opens and the SCR starts to conduct. Once the gate voltage is removed, the SCR remains in the “on” state, in other words, it will continue to conduct current until the current is reduced to a point where it can no longer conduct. This is known as the repeting mechanism of the SCR.

The gate of the 2N1806 is controlled by the gate signal, which is typically a signal generated by a microcontroller or other logic circuit. With the gate signal, the 2N1806 can be switched on and off, enabling it to provide regulation of current, or on/off switching of a load. The gate signal can also be adjusted to vary the on/off switching characteristics of the 2N1806, allowing for a wider range of applications.

The 2N1806 is a versatile and reliable Thyristor — SCR — that can be used for a wide range of applications. It is capable of regulating voltage and current levels, switching on and off of loads, and providing protection from overvoltage and overcurrent faults. With its flexibility and dependability, the 2N1806 is an excellent choice for a variety of applications.
