Thyristors - SCRs

VS-ST230S16P1 Application Field and Working Principle

Thyristors are a class of electronics components designed to work as one way switches, allowing electricity to flow in one direction and blocking electrical current in the reverse direction. SCRs (silicon controlled rectifier) is one type of thyristor and the VS-ST230S16P1 is such a device. This article covers the application field and working principle of the VS-ST230S16P1.ApplicationsThe VS-ST230S16P1 is mainly used in switching and rectification applications. It is specifically designed for AC control and DC motor drives. This device can control switching for loads up to 150V / 8A and provide electrical insulation up to 2500VAC.The VS-ST230S16P1 can be used in multiple fields such as:* Automotive: Automotive applications mainly include fuel and spark ignition, headlamp blower, ABS systems and electronic engine controls.* Industrial: Industrial applications includes welding machines and solenoid valves.* Home appliances: Home appliances such as air-conditioners and washing machines often use the VS-ST230S16P1.Working PrincipleThe VS-ST230S16P1 is a three-terminal, four-layer thyristor device. It contains two J-E junctions, which are connected in series. This device is triggered by the gate voltage which produces a current that causes the two J-E junctions to start forward conducting. When this thyristor is off, it acts as a reverse biased diode and no current can flow through it. When it is turned on, it works as an SCR and allows electrons to move through it in either direction when it is connected to an external circuit.The voltage across the thyristor is limited by the device\'s "breakover" voltage, which is the minimum voltage that needs to be applied across the terminals in order for the device to begin conducting current. When the voltage exceeds this breakover voltage, the current flow increases exponentially and the device begins conducting.The gate trigger voltage applied to the device controls the breakover voltage, allowing the user to control the amount of current flowing through the device. The gate voltage also controls the amount of time that the thyristor spends in the on-state before it automatically switches off due to time-dependent conduction. ConclusionThe VS-ST230S16P1 is an SCR which is mainly used for switching and rectification purposes in multiple fields such as automotive, industrial, and home appliance. Its working principle is based on the two J-E junctions that are part of the device and its gate voltage, which controls the breakover voltage and the amount of time in the on-state. The VS-ST230S16P1 can handle up to 150V / 8A and provides electrical insulation up to 2500VAC.
