A thyristor is an electronic device used to control electric current. A wide variety of thyristors exist, such as DIACs, SIDACs, and the K1200E70RP specifically. Although all of these products have different characteristics and applications, they all share the same basic working principle.

K1200E70RP Application Field

The K1200E70RP is a thyristor designed for use in low voltage industrial applications such as lighting, motor control, and HVAC systems. It has a wide operating range of 0-280 volts, and is capable of switching up to 40 amperes of current. It has a low on-state voltage drop of 1.6 volts, and its on/off switching has superior reliability. Due to its low profile, it can also be used in space-constrained applications.

K1200E70RP Working Principle

The K1200E70RP works by responding to a small amount of current (gate current). This trigger current causes the thyristor to turn ON and allow the flow of current. Once the current is flowing through the thyristor, it remains ON until the current is interrupted. When the thyristor is ON, its on-state voltage drop (Vdrop) is 1.6 volts. This voltage drop causes a power loss, which is why it is important to have an adequate heat sink to dissipate the heat generated by the thyristor.

DIACs and SIDACs

DIACs and SIDACs are two types of thyristors that are similar to the K1200E70RP in terms of their operation. DIACs and SIDACs both require a small gate current to be applied to them in order to turn them ON, however, the trigger current for DIACs is significantly lower than for SIDACs. Additionally, DIACs have a lower on-state voltage drop than SIDACs, which means they can handle higher currents with less power loss. DIACs are typically used in low voltage applications, while SIDACs are usually used in higher voltage applications such as HVAC or automotive systems.

Thyristors, and specifically the K1200E70RP, DIACs, and SIDACs, are a critical component for controlling electrical current. They can be used for a wide variety of applications, with the K1200E70RP being specifically designed for low voltage industrial applications. By understanding their operating principles and features, designers can select the most appropriate thyristor for their application.
