Thyristors - SCRs - VS-110RKI80 application field and working principle

The VS-110RKI80 is a series of Thyristors - Silicon Controlled Rectifiers (SCRs) that is manufactured and sold by Vishay Intertechnology, Inc. It is used in a wide variety of applications, from AC and DC motor controllers to overload protection and power supplies. The SCR is a four layer solid state electronic device consisting of an anode, cathode, and two control electrodes, which are referred to as the gate and the trigger. SCRs are typically used as switches, either turning on or off an electrical load when a predetermined voltage or current is applied to it.The VS-110RKI80 is a high power rated SCR, intended for use in high voltage and current applications. The device utilizes a low turn-on voltage and short reverse recovery time, making it ideal for applications where fast switching times are required. Its fast switching time is achieved through the use of an internal diode. This diode allows a current to flow through the SCR quickly when the gate or trigger electrode is applied with a voltage or current greater than its turn-on threshold.The VS-110RKI80 series of SCRs has a range of characteristics that make it well suited for various applications. It is a rugged, robust component that is capable of withstanding high voltage and current, and is suitable for use in harsh or extreme environments. It features a low trigger current and wide operating temperature range, making it ideal for use in switch mode power converters, motor speed/voltage controllers, and other applications requiring high power and fast switching times. Additionally, the low turn-on voltage and short reverse recovery time of the VS-110RKI80 allow it to be used in power converters and other switching circuits that require precise control of on and off switching times.The VS-110RKI80 is capable of handling large amounts of power and is able to survive the high levels of noise and temperature associated with several types of applications. It has a maximum continuous current rating of 800 A, a peak non-repetitive surge current rating of 3000 A, and a peak repetitive surge current rating of 1200 A. The device transistors can handle up to 1100 V of steady-state DC, and its maximum on-state voltage is 400 V.The VS-110RKI80 SCR is designed to be both reliable and easy to use. It has standard solder pin connections and mounting holes for ease of installation. Additionally, the device features a built-in anti-saturation circuit that prevents SCR\'s conduction region from becoming over-saturated, ensuring smooth and safe operation. This device is also RoHS compliant, making it suitable for use in the most environmentally-friendly product designs.The VS-110RKI80 SCR is a versatile and reliable device that has been successfully used in a variety of applications. From motor speed controllers to power supplies, this robust component offers high power rating, fast switching times, and easy installation. With its many advantages, the VS-110RKI80 is an excellent choice for projects requiring reliable and precise control of switching signals.
