Thyristors are a variant of transistors comprising three or four layers of semiconductor sandwiched between two electrodes. Thryistors have been in use for a long time and can be used to switch or modulate an electric current. It is the SCRs or Silicon Controlled Rectifiers, which are mainly used due to their efficient switching, high current capability and energy efficiency.

SCRs consist of four layers of semiconductor material, two of which are "P-type" and two of which are "N-type". These layers are arranged between two metal contacts called the Anode and the Cathode. When the Anode is connected to a positive voltage and the Cathode to the negative voltage, then a voltage is applied to the Gate of the SCR. The Gate of the SCR is the third electrode between the Anode and the Cathode. When the Gate is activated a small electric current passes through and allows larger current to flow from the Anode to the Cathode. This process is known as triggering or turning on the SCR.

The S2010V is a type of SCR and it is most commonly used for AC voltage and current control, motor speed control, surge current control and other similar applications. It is a popular choice due to its reliability, ease of use and energy efficiency. The S2010V has a maximum rated forward current of up to 10A, a maximum rated reverse voltage of up to 40V, and a peak gating current of up to 3mA. It can operate at temperatures ranging from -40°C to +85°C.

The working principle of the SCR is based on the PN junction diode. When the Gate voltage reaches the breakdown voltage of the diode, then a small current will flow in the Gate region. This current will cause the PN junction of the diode to conduct and a large current will flow from the Anode to the Cathode of the SCR. The Gate voltage is referred to as the control voltage and is used to turn the SCR on or off. When the control voltage is removed, the SCR will cease to operate and the current between the Anode and the Cathode will be interrupted.

In summary, the S2010V SCR is a popular choice due to its reliability and energy efficiency. It is commonly used for AC voltage and current control, motor speed control, surge current control and other similar applications. The working principle of the SCR is based on the PN junction diode and the control voltage is used to switch the SCR on or off.
