Thyristors - SCRs, or Silicon Controlled Rectifiers, are a special type of semiconductor device that for the most part has replaced the mechanical relays, contactors and power contacts used in the past. Thyristors are especially useful in applications that require high switching capacities and current-carrying capacity. The 2N2328 is a thyristor commonly used in such applications.

The 2N2328 is a four-layer semiconductor device, typically made up of two p-type, and two n-type semiconductor layers. The p-type layers form the anode, and the n-type layers form the cathode. When current flows from the anode to the cathode, it triggers a Gate Control Input (GCI), and the device enters the “on” state. Once in the “on” state, the current will continue to flow from the anode to the cathode, until the current is removed or the GCI is disabled. The 2N2328 is a very popular thyristor because of its low cost and fast switching speed.

The 2N2328 application field includes industrial motor speed control, HVAC systems, welding controls, power regulation, lighting controls, and in medical equipment. Additionally, it can be used in ac-dc motor control, LED lighting, and traffic signals. The thyristor can also be found in some electronic toys, remote-controlled toys, switch-mode power supplies, and some light dimmer and flood lights. The 2N2328 is also used for the control of static converters and variable-speed AC motors.

The working principle of the 2N2328 is that it is a thyristor device that utilizes a gate control input (GCI) to switch it on and off. When there is no current, the thyristor is open and no conduction occurs. However, when a small voltage is applied between the anode and the gated cathode, the GCI activates the device, and current then flows from the anode to the cathode. The current will continue to flow until the gate voltage ceases or the current is removed. The 2N2328 is also capable of handling high current and voltages and is an excellent choice for power controlling applications.

The 2N2328 thyristor has been popular in many industries due to its low cost and fast switching speed. It can be found in a wide range of applications such as industrial motor speed control, HVAC systems, welding controls, power regulation, lighting controls, medical equipment, and many other fields. By understanding the working principle of the 2N2328, it is easy to see why it has become the go-to thyristor for powering and controlling industrial equipment.
