Thyristors are semiconductor devices that can act as switches, with either an “off” or “on” state, to regulate the flow of electrical current. They are mainly utilized in power-related applications, such as controlling motors and large electrical loads. The types of thyristor devices largely depend on the application, but generally fall into one of the three categories: triacs, DIACs and SIDACs. In this article, we will discuss the ST32B application field and working principle of DIACs and SIDACs.
DIACs (Diode-Actuated Controlled Switches) are one of the most common thyristors. They are used to turn the power “on” and “off,” in a repeated but never completely predictable way. This has the benefit of preventing electrical surges and managing the power of large devices. The ST32B is a type of DIAC which uses a rising-edge trigger, meaning that when its threshold voltage is reached, its ON-state speed is greatly increased.
The ST32B application field can be quite versatile, but traditionally it has been used for high-power applications such as lighting circuits and starting electric motors. It is also used in AC power relays for high-voltage switching applications. The ST32B is also popular in industrial instrumentation, as well as automotive applications.
The working principle of a DIAC is based on the fact that, when the current passing through it reaches a certain threshold, it begins to conduct. This occurs due to a positive resistance curve, which means that the current passing through the diode gradually increases as more voltage is added to the circuit. The threshold voltage of the ST32B is typically between 80V and 300V.
SIDACs (Static Induction Thyristors) are similar to DIACs, but are designed specifically for use with AC circuits. SIDACs are capable of controlling currents of up to 10A and voltages of up to 400V. They are used in applications that require a fast on-off switching, such as general-purpose solid-state relays.
The ST32B is a popular SIDAC, with a positive temperature coefficient of up to 0.5. This means that it can maintain a stable temperature range throughout its range of operation, which is ideal for operations under varying conditions. It is also capable of dealing with high frequencies, allowing it to be used in fast on-off switching circuits.
The working principle of a SIDAC is similar to that of a DIAC. When the current passing through the device reaches a certain threshold, a thyristor forms, allowing the device to act as a switch. The current can then be turned on and off repeatedly until it reaches its breakdown voltage.The ST32B is a popular choice for applications requiring a fast and stable operation. Its positive temperature coefficient and high-frequency handling capabilities make it ideal for high-power and high-frequency applications. It is easy to use and widely available, making it an excellent choice for a variety of applications.
