Thyristors - SCRs - Modules

A silicon-controlled rectifier or thyristor (SCR), also known as type VVZB120-12IO1 is an electrical component that can be used for controlling the flow of electrical power to a load in a circuit. It is a two-terminal, four-layer semiconductor device that acts as a switch for controlling the amount of current flowing through a circuit. The SCR can be turned on and off electrically, thus making it very versatile for use in a variety of applications.

VVZB120-12IO1 Application Field

The VVZB120-12IO1 is used in a variety of high current, high voltage applications. These might include controlling power in a motor, controlling the speed of machinery through a speed controller, or controlling the intensity of a light bulb in a lighting circuit. The ability to control the current means the module can be used in a variety of situations where precise control of the power or intensity of a load needs to be accomplished. The VVZB120-12IO1 module is also often used in computers as a component of voltage regulators.

VVZB120-12IO1 Working Principle

The SCR contains two primary elements, the Gate and the Anode. The Anode, typically the larger of the two, is connected to positive voltage. The Gate is connected to a control signal, and provides control over the current flow between the Anode and the Cathode. When the Gate is open, no current is allowed to flow between the Anode and the Cathode. When the Gate is closed, the Anode can become charged, which allows current to flow between the Anode and the Cathode.When the VVZB120-12IO1 is used to control a motor, the Gate is connected to a signal from a microprocessor or other control source. When a power signal is applied to the Gate, the Anode and the Cathode become connected, allowing current to flow and the motor to turn. When the power signal is cut off, the Anode and the Cathode are no longer connected and the motor ceases to turn.The VVZB120-12IO1 is part of a larger family of Thyristor components and modules, which includes SCRs, Triacs, and Backtos. These components differ in their physical design, but work in a similar fashion to the VVZB120-12IO1 module, allowing precision control of power in a variety of applications.
