Thyristors are semiconductor devices that are commonly used in electrical circuitry. The functionality of these devices is based on the principle of switching-on and -off power supply with the help of a switch. There exist two types of Thyristors - SCRs (Silicon Controlled Rectifiers) and Triacs (Triode For Alternating Current). SCRs and Triacs are energy controlling devices, employed in various applications, such as controlling electric motors, lighting and heating equipment, electric fence systems, and some high power switching purposes. The VS-ST083S08PFM0P is an example of such an SCR, used in various industrial and commercial applications. Specifically, the VS-ST083S08PFM0P is a hybrid rectifier SCR, which means it is both a rectifier and an SCR. It is a four layer, isolated, four pin device which provides basic protection and control, including soft start and high frequency switching up to 50 kHz. It also has a wide operating range from -40C to 85C, a wide operating voltage from 800V to 1600V, and can handle a large number of pulses.A pre-designation for the VS-ST083S08PFM0P is an electric bridge rectifier. It performs the same function as a two diode bridge rectifier when controlling the voltage. In contrast to the diode bridge rectifier, however, the VS-ST083S08PFM0P has more features, such as high noise immunity, high creepage, wide operating temperature range and higher on-state current capability.The main working principle of the VS-ST083S08PFM0P is based on the thyristor’s function. As mentioned previously, it acts as an electric bridge rectifier, in which current flows through the SCR when the gate voltage is higher than the anode voltage. As long as the gate voltage is applied and the mains voltage rises above the gate voltage, the SCR will let the current pass through. When the mains voltage drops below the gate voltage the current will no longer pass and the SCR will turn off. The SCR will remain in this off-state until the gate voltage is applied again.The VS-ST083S08PFM0P can be broadly applied in power supplies, UPSs, high frequency welding and soldering, DC motor control, lighting, electric vehicle chargers, renewable energy systems, and solar inverters. For instance, the VS-ST083S08PFM0P can be used as a high speed switching element for DC motor control, in order to turn the motor on and off, as well as regulate its speed.In conclusion, the VS-ST083S08PFM0P is an SCR (Silicon Controlled Rectifier) in the form of a hybrid rectifier, with wide operating range and a high operating voltage, up to 1600V. It has high noise immunity, high creepage and wide operating temperature range, making it suitable for a multitude of industrial and commercial applications. The VS-ST083S08PFM0P’s function is based on the thyristor’s functioning principle, i.e. it acts as an electric bridge rectifier, in which current flows through the SCR when the gate voltage is higher than the anode voltage.
