Thyristors are semiconductor components that are mainly employed in the field of electrical engineering. They can carry out a variety of functions such as the regulation of electrical current and the conversion of DC current to AC current, among others. There are three major types of thyristors: the silicon controlled rectifier (SCR), the gate turn off thyristor (GTO), and the static induction thyristor (SITh). Today, we will be focusing our attention on the SCR type thyristor, with a specific look at the JAN2N2328 type.

The JAN2N2328 type SCR is a robust device that has a power capacity of up to 400W and a wide operating temperature range from -65°C to + 200°C. It is also capable of withstanding voltages up to 200V and has a high surge current rating of 8A. This SCR is used primarily in applications that require repetitive and high-speed switching, such as motor speed control circuits and relay contactors. It also has applications in integrated logic circuits, AC/DC conversion and electrical power systems.

The working principle of the JAN2N2328 type SCR is simple. It consists of four P-N junctions joined together to form a four-layer semiconductor structure. The four P-N junctions are arranged in an "H" shape, which is the reason why it is also called a four-layer diode. When +V is applied to the gate, the SCR will be triggered, allowing a flow of current through the SCR structure. To deactivate the SCR, a negative voltage must be applied to the gate.

In conclusion, the JAN2N2328 is a robust SCR whose versatile applications meet the needs of many electronic applications. Its wide operating temperature range, high surge current, and 400W power capacity make it a reliable and convenient choice for a variety of applications. Its simple working principle of applying +V to the gate to trigger it and applying negative voltage to deactivate it makes it easy to understand and use.
