Thyristors - SCRs encompass devices that are capable of controlling the flow of electric current in an electronic circuit. These devices use the electron-hole injection process to control the current.

SK012R is a type of High Voltage Thyristors - SCRs that is used for a variety of applications, such as Motor Speed Control, AC Motor phase control, Power switching, and DC Motor phase control. It is capable of handling currents ranging from 50 to 600A. The device can be operated on an input voltage between 75V and 650V.

The SK012R is composed of two sections: an anode region and a gate region. The gate region consists of a control electrode, called the gate, and a set of electrodes connected to the gate. The anode region consists of another set of electrodes connected to the anode or main terminal. When the gate receives a signal, it charges the electrode and causes a current to flow in the anode region.

The working principle of the SK012R is based on the principle of electron-hole injection. When a certain amount of gate signal is applied, an electron-hole pair is created in the device, which allows current to flow through it. This current allows the anode to activate and control the flow of electrons through the anode region. The current can then be directed to the appropriate load circuit.

In order to avoid over-voltage and over-current conditions, the SK012R includes built-in protections, such as thermistors and temperature guards. The thermistors limit the current flowing through the device and the temperature guards protect the device from overheating. Additionally, the device includes a protection circuit to help limit arc voltage. This reduces the risk of device damage from over-voltage.

The SK012R is well-suited for a variety of applications where high current needs to be controlled. It is a reliable, cost-effective device and is widely used in Motor Speed Control, AC Motor Phase Control, Power Switching, and DC Motor Phase Control.
