A 2N6784 is a two-terminal, one-junction device that belongs to a category of field-effect transistors (FETs) known as monolithic silicon-controlled rectifiers (SCRs). These devices are commonly used in a wide range of electronic circuits to control, regulate and protect a variety of switches, motors, and other electronic components. Unlike transistors, SCRs operate by utilizing a special feedback process that allows current to flow only in one direction, thus providing a simple and reliable means of controlling DC switching operations.

The 2N6784 works by utilizing a three-layer, p–n–p symmetrical structure containing a layer of N-type semiconductive material which forms the bulk of the device. This middle layer, which is referred to as the control electrode, is responsible for the regulation of the current flow through the semiconductor. When an electric current is applied from one terminal of the device to the other, it causes a charge imbalance in the middle layer, resulting in a field effect which, in turn, modulates the current flow between the two terminals.

The 2N6784 can be used in a variety of devices and integrated circuits for the purpose of controlling and managing the DC switching operations. For instance, it is ideal for use in applications such as resistors or current sensors and may be used to switch on and off the power supply to other components. Additionally, this device can be used as a multivibrator to produce precise timing intervals as required in many electronic latching or delay operations. Furthermore, it can be used as an amplifier in various amplifier circuits.

The working principle of the 2N6784 is quite simple. When current is applied to the device through its two terminals, the middle layer of semiconductor material modulates the current flow in either a positive or a negative direction depending on the voltage levels of the two terminals. This modulation of the current flow is used to control the operation of various electronic components. For example, when an SCR is connected in series with a switch or motor, the activity of the switch or motor can be remotely controlled as the SCR will start or stop the current flow through it depending upon the amount of current applied to it.

In conclusion, the 2N6784 is a highly versatile and reliable two-terminal device that is ideal for use in a variety of applications. It works by utilizing a field effect which modulates the current flow from one terminal to the other, thus offering a reliable means of controlling the switching operations of different components. It can be used for a variety of purposes such as resistors, current sensors, multivibrators, amplifiers and more, thus making it an essential FET device in any circuit.
