VS-22RIA120 Application Field and Working Principle

The VS-22RIA120 is a silicon controlled rectifier Thyristors (SCR) from General Semiconductor and is an example of modern engineering. It is suitable for applications such as DC Motor Speed Control, Variable Lighting and Soft-start applications. It is also used to control the load of various industrial and household electrical appliances.The VS-22RIA120 is a single phase, twelve amp SCR Thyristor. It has low turn-on and switching losses, high efficiency, and controlled symmetrical characteristics, making it a reliable choice for automatic control circuit. The VS-22RIA120 is rated at 600V AC, 50-60Hz and its current capability is rated at twelve amps with a load resistor current share ratings of 8.5A. It has a low leakage current, excellent AF characteristics and a wide operating temperature range. The working principle of an SCR Thyristor can be demonstrated with an example of a basic light dimmer circuit. In this example, a potentiometer is used to alter the voltage and accordingly, the current passing through the SCR Thyristor. With an increase in the voltage, the gating current increases, when the gating current reaches its forward ubreakover current, the Thyristor turns on, allowing a controlled current flow through it. With a decrease in voltage, the gating current decreases, when the gating current drops below its reverse breakover current, the thyristor turns off, cutting off the current flow.The VS-22RIA120 also has several other features that make it a desirable choice for applications such as power supplies, inverters and switching systems. It has an onboard air mounted construction, an externally mounted 200 ohm gate resistor, and a 150 ohm lightning protection resistor for enhanced safety. Its oversized silicone insulated leads ensure reliable and secure contact, and it is able to handle high temperature and vibration. Additionally, it has a latch-proof design and a galvanized steel case for added protection from dust and other contaminates.In summary, the VS-22RIA120 is an ideal solution for applications that require robust and reliable switching, such as motor speed control, variable lighting and soft-start applications. It has several features that make it a desirable choice, including a low turn-on and switching losses, a high efficiency, controlled and symmetrical characteristics, an onboard air mounted construction, an externally mounted 200 ohm gate resistor, a latch-proof design, a galvanized steel case, and oversized silicone insulated leads.
