Thyristors are semiconductor devices that can be used to control the flow of electrical energy to an electrical load. Among the various thyristors are DIACs, SIDACs, and the K1400S1URP. These thyristor devices each have their own application field and working principle.DIACs, or diacs, are bidirectional devices that are typically used to trigger thyristor devices when a specific voltage is reached. They act as a sort of switch, allowing current to pass through when the required voltage is reached. In addition, they also provide short-circuit protection as the voltage on the device does not rise above a certain level. The working principle of DIACs is that they use a circuit containing two diodes connected in series with a resistor between them. This is used to prevent the voltage across the device from increasing beyond a specific level.SIDACs are also bidirectional devices, but they are significantly different from DIACs in terms of their application field and working principle. SIDACs are primarily used for surge protection, as they allow a high voltage to be safely discharged over time. Unlike DIACs, SIDACs have a much larger conduction angle and can therefore act as a switch for higher voltages. The working principle of SIDACs is that a gate voltage is applied to the device, which causes the voltage threshold to be reached at which point current will pass through the device.The K1400S1URP is a thyristor device that has a unique application field and working principle. It is used as a high-speed switching device, and is capable of switching currents up to 2000A. The working principle of the K1400S1URP is based on providing a positive gate voltage in order to initiate conduction. The device is triggered when the latching current is reached, at which point the voltage across the device will quickly rise.In conclusion, DIACs, SIDACs, and the K1400S1URP are all thyristor devices that have different application fields and working principles. DIACs are used to trigger other thyristor devices when a specific voltage is reached, SIDACs are used for surge protection, and the K1400S1URP is a high-speed switching device capable of switching currents of up to 2000A. All of these devices rely on the principles of a thyristor circuit, but each have their own unique characteristics that make them appropriate for different applications.
