A thyristor, also known as a silicon controlled rectifier (SCR), is a three-terminal semi-conductor device consisting of two PN junction diodes connected in opposition and controlled by a gate current. In its conducting state, it behaves like a switch with high current carrying capacity and low on-state voltage drop when compared to that of a diode. The 2N682 SCR is a robust, miniature device suitable for switching applications in the industrial, transportation and consumer markets. It is designed to provide reliable performance when controlling the switching of motors and lighting, especially in environments where shock and vibration are likely to occur.

The 2N682 thyristor family is designed with a low triggering current, allowing it to switch on in response to a signal from as low as 3mA. This current can also be supplied by an integrated circuit, making the device suitable for a wide range of applications. The 2N682 is also designed to have a high blocking voltage making it an ideal choice for high-voltage circuits. Its maximum blocking voltage is 400V and its A.C current rating is 16A.

The 2N682 SCR has a direct relationship between the gate current and the amount of current that is allowed to flow through the device. When a gate voltage is applied, a small current (IGT) begins to flow through the gate-cathode junction. This current increases the forward potential of the junction between the gate and cathode and is responsible for allowing more current to flow through the device. When the gate voltage is removed, the current stops flowing and the device is off.

The 2N682 SCR is a popular choice for AC applications because of its ability to control the power delivery of LEDs, motors and other devices. It is particularly effective in circuits or devices that require fast switching since it is capable of switching the state of the AC current in a matter of microseconds. In addition, the 2N682 SCR is well suited to applications such as welding and battery charging since its high blocking voltage makes it ideal for switching high-voltage loads.

The 2N682 SCR is a versatile device with a host of applications, but can be a dangerous tool in the wrong hands. It is important to be aware of the risks associated with the device, and to take proper precautions when using it. For example, negative voltages can cause the SCR to switch suddenly, leading to hazardous currents and operation. In addition, the SCR should be connected properly and not be exposed to conditions of extreme temperature or humidity.

In conclusion, the 2N682 SCR is a robust and reliable device that has a wide range of applications. It is suitable for use in high-voltage circuits and can handle current up to 16A, making it a great choice for switching a variety of loads. However, it is important to understand the risks associated with the device and take the necessary precautions when using it.
