Thyristors - SCRs – CS218-35P Application Field and Working Principle

The CS218-35P is a silicon controlled rectifier (SCR), which is a type of thyristor that\'s often used in applications which require low power switching, current steering, and speed control. This type of SCR is designed for applications that require a controllable amount of current including power supplies, AC power controllers, motor control systems, temperature control systems, lighting control systems, and other such applications. It\'s an important component that is needed for any system that requires an on/off power supply.The basic internal structure of an SCR is made up of two back-to-back PN junctions, with each PN junction having four leads, commonly known as anode, cathode, gate, and emitter. The main purpose of the gate is to control the flow of current between the anode and cathode. An electric field is generated between the gate and cathode terminals, allowing the current to flow once the gate is triggered. The main principle behind the working of the CS218-35P relies on the conduction of current once it\'s triggered.When the SCR receives positive current at the gate terminal, a steady direct current begins to flow between the anode and cathode. This current continues to flow as long as the gate terminal is connected. In order to switch off the SCR, negative current is applied to the gate terminal, which temporarily stops the flow of current between the anode and cathode. When the negative current is removed from the gate terminal, the steady current resumes its flow.In order to make better use of the CS218-35P, several techniques are employed to provide maximum performance from the SCR. One such technique is to use a dv/dt protection system, which is used to protect the SCR from abrupt changes in voltages and currents. Another technique is to make use of a spike suppressor, which is used to suppress the high amplitude spikes that can be generated during the switching of the SCR.The CS218-35P is highly reliable and versatile, allowing it to be used in a wide range of applications. The SCR can be used in AC power controllers, motor drives, relay control systems, and many other types of applications. Its features such as low loss switching, current control, and flexibility in applications make it an ideal choice for various industrial applications.The CS218-35P is also a reliable and durable SCR, with a long life span due to its robust build. It can handle up to 6.5 volts, with a peak surge rating of 3 Amps. It also supports high-frequency switching, which makes it ideal for faster response systems. Additionally, it can operate in temperatures ranging from -25 to +85 degrees Celsius, making it suitable for a wide array of applications.Overall, the CS218-35P is one of the most reliable and versatile SCRs available on the market. Its ability to handle high voltages, current and frequency make it a perfect choice for a variety of industrial applications. It is also highly durable, with an extensive life span, which makes it an ideal choice for a wide range of applications. Its ability and features make it a popular choice among industry professionals.
