Thyristors - SCRs - Modules: VS-VSKH26/10 Application Field and Working Principle

Thyristors are a type of semiconductor device widely used in many applications today ranging from power supplies and motor drives to telecoms. They are particularly suited for use in high current switching applications, because of their extremely low forward voltage drop and very fast switching times. The part of the thyristor family of components that is most commonly used in these applications is the SCR (silicon controlled rectifier), and one of the most popular SCRs available is the VS-VSKH26/10. In this article, we will discuss the VS-VSKH26/10\'s application field and working principle.The VS-VSKH26/10 component is a silicon-oxide-nitride-oxide-silicon (SONOS) structure SCR, so it is suitable for use in high-temperature and high-voltage environments. It has a maximum avalanche current of 175A, a minimum avalanche current of 75A, and a maximum reverse voltage of 400V. This SCR is commonly used in power supplies, motor drives, servo motors, and telecom applications that require fast switching speeds and reliable performance. In terms of the SCR\'s working principle, the device works by conducting current when the gate voltage is applied. When the gate voltage is applied, the thyristor is triggered and it switches on and begins conducting current. The SCR remains in this \'on\' state as long as the gate voltage is maintained. The conduction of current can only be stopped by a reduction in the voltage from the gate, and so the device works very reliably in high-current switching applications.The application of the SCR in the power supply field is particularly efficient and reliable due to its fast switching times, low forward voltage drop, and superior temperature stability. It is used in AC-DC and DC-DC power supplies to regulate the current and provide surge protection. The dielectric characteristics of the SCR make the device very suitable for the protection of sensitive areas in telecom applications. It is commonly used in base stations, T1, and E1 communications, and in cellular phones.The SCR is also used in motor drives and servo motors due to its fast switching times and low forward voltage drop. The SCR\'s fast switching capability is also useful in robotic applications, where it is used to control the rapid motion of various robot parts.Overall, the VS-VSKH26/10 SCR is a very popular component due to its high performance in a wide range of applications. Its dielectric stability, low forward voltage drop, fast switching times, and superior thermal characteristics make it the perfect choice for sensitive applications such as telecom and power supplies. Additionally, its fast switching times make it particularly suitable for use in motor drives and servo motors.
