Thyristors are devices that are used in applications such as surge protections, current limiting, phase control, AC and DC motor control, battery chargers, fuse cut outs, and a host of other control and SCR/thyristor applications. SCR (silicon controlled rectifier) is one of the most used members of the thyristor family. It is a four-layer, three-terminal, nonlinear solid state device. SCRs are used in applications such as AC and DC motor control, power conversion, power conditioning, and rectification.

The S2010FS21 is a standard gate triggerable thyristor, meaning it can be triggered by applying a positive gate voltage. It is designed to control large amounts of current in medium- and high-power applications. It comes with a concentrated insulated gate and a rated blocking voltage of 600V with a DC current of 10A.

The structure of the S2010FS21 device consists of a silicon controlling the rectifying junction. When the correct gate-to-cathode voltage is applied, the device begins to turn on, allowing current to flow through the main anode to cathode junction. Once the gate voltage is removed, it returns to its non-conductive state.

The gate of the S2010FS21 can be triggered using both AC and DC signals. When using a DC signal, the gate needs to be at a positive potential of more than the junction trigger point of 1.6V to trigger the thyristor. If a DC voltage is connected between the gate and cathode but lower than the junction trigger point voltage, the thyristor will not turn on.

When using an AC signal, the gate must have a voltage of peak-to-peak or above the junction trigger point to turn on the thyristor, as the peak of the AC signal switches the thyristor on, and the anode-to-cathode voltage should be set such that the forward voltage does not exceed the maximum steady state forward current rating.

The S2010FS21 provides both positive and negative Gate Turnoff (GTO) options. The GTO system allows the thyristor to be turned off remotely without affecting other devices connected to it. This helps reduce the effects of thermal runaway and increase the safety of the system.

The S2010FS21 thyristor has a wide range of applications such as motor control, power conversion, rectification, relay protection, and other various pulse circuit applications. It can also be used in applications that involve high-current and high-voltage load switching, such as in electrical furnaces and other high-power loads.

In summary, the S2010FS21thyristor is a highly efficient and reliable device that can be used in a wide range of applications from motor control to power conversion and rectification. Its ability to be triggered both with AC and DC signals, as well as its positive and negative GTO system, make it a very versatile device that can be used in many different applications.
