Thyristors - SCRs

MCR12DG thyristors are designed for use in general purpose AC, DC and magnetic amplifier applications. They are also suitable for voltage regulation, motor speed control, high-power switching and peak power control.The MCR12DG is a silicone Controlled Rectifier (SCR), which is a semiconductor device, commonly used in AC and DC power control circuits. An SCR is basically a two-terminal solid-state switch that is electronically controlled. It consists of three, four or more layers of semiconductor materials. It is used to switch current or wall voltage on or off by controlling the gate voltage.When a positive gate voltage is applied to an SCR, it will turn on and will allow current to pass through it until the main current is interrupted by another means, such as phase control or by the removal of the gate signal. When the current is stopped, the SCR turns off and no current is transferred.The MCR12DG is designed for use in AC line applications, such as heavily loaded AC motor control, AC power control and phase angle control. It also finds uses in DC power control such as low voltage DC motor speed control, rectification of high-frequency AC waveforms, and as a DC power controller. Additionally, it can be used for AC voltage regulation or lighting control.When a positive gate pulse is applied to an MCR12DG, it will start conducting and the current flow can be controlled by varying the gate voltage from zero to a positive voltage. A positive voltage will increase the current while a negative voltage will reduce the current. The MCR12DG is capable of controlling up to 12 amps of current at up to 600 volts of voltage. It is also equipped with special circuitry to regulate the current and voltage in order to ensure safety and reliability. As with other types of thyristors, the MCR12DG can be used in high power control circuits. For example, it can be used in ultra-high power switching applications such as induction heating, furnaces, rectifiers, in addition to lighting control and peak power control. In short, the MCR12DG is an ideal choice for a variety of applications requiring reliable power control. It is designed to provide excellent performance and its wide range of features make it an attractive option for a variety of industrial, automotive and consumer applications.
