Thyristors are three-terminal semiconductor devices that act like back-to-back two-terminal diodes, thus comprising three PN junctions. A thyristor is a component of a larger device, such as a silicon controlled rectifier (SCR), which is a three-terminal device that has controllable switching and rectification capability. One of the commonly used SCRs is the 2N2328AS.

The 2N2328AS is a four-layer, bidirectional silicon controlled rectifier (SCR) rated for a breakdown voltage of 76.5 volts and an off-state voltage of 2 volts. It is a medium-power device, operating in the positive gate to negative anode direction and designed for use in rectifiers, motor controllers, relays, and power supplies. Its operating temperature range is from -40 °C to +125 °C.

The main application field of the 2N2328AS is in AC switching circuits such as kilowatt-hour meters, adjustable-speed motor drives, solid-state heating controllers and industrial load controllers. The 2N2328AS can also be used in many power electronics applications such as H-bridge motor control, phase control, lamp controllers, and input rectification.

The working principle of the 2N2328AS is the same as other SCRs. When a positive voltage is applied to the gate of the 2N2328AS, it creates a current in the gate terminal, which causes current to flow from the anode to cathode of the SCR. The current then causes the SCR to become non-conductive, which enables the SCR to switch on and off depending on the voltage applied to the gate terminal. The 2N2328AS can be switched on and off quickly, which makes it suitable for applications requiring fast switching.

The 2N2328AS is an economical and reliable device that can be used in a wide range of applications. It is a rugged and versatile device that operates reliably in temperatures ranging from -40 °C to +125 °C. The device also has a low on-state voltage drop, which helps reduce power losses in applications.

The 2N2328AS is a cost-effective and reliable solution for many AC switching and power electronics applications. It is a rugged and versatile device that operates efficiently and can be used to switch on and off quickly. Understanding the application field and working principle of the 2N2328AS is key to its successful implementation in various applications.
