Thyristors - SCRs (Silicon Controlled Rectifiers) are power electronic switching devices used to control and regulate current. They are widely used in AC power systems, motor control, and large home appliances. The VS-ST180S12P0VPBF is a type of SCR manufactured by Vishay Intertechnology, Inc. and is designed for power applications in which a high current, low voltage switch is needed. This application note will discuss the applications fields and working principle of the VS-ST180S12P0VPBF.

The VS-ST180S12P0VPBF is a thyristor SCR with a current rating of 180A at 12V DC. It features a fast switching speed and low turn-on voltage of 83V DC, making it well suited for applications such as motor control, AC power switching, and fan and compressor control. Additionally, its lead-free construction and RoHS compliant packaging make it an environmentally friendly option for power switches.

When designing circuits with SCRs, it is important to note that SCRs behave differently than standard transistors in that they remain in the “on” state once the gate signal has been applied, until the current drops to zero. This behavior is known as “latching” and allows SCRs to be used in circuits which require repetitive switching. In order to turn the SCR off, we must reduce the current flowing through it to zero. This can be done by moving the gate signal to a negative voltage while the current is still flowing.

The VS-ST180S12P0VPBF is popularly used in applications such as motor control, AC power switching, and large home appliances due to its ability to switch rapidly and its small form factor. In motor control systems, it can be used to switch the direction of current to switch the motor on or off, or to regulate the speed. In AC power switching applications, it is used to switch the power supply on or off, or to switch to emergency power supplies. In large home appliances such as refrigerators and freezers, it can be used to switch the compressor on or off, or to regulate temperature.

The VS-ST180S12P0VPBF works on the principle that when a small control current is passed into its gate terminal, it latches into a conducting state and remains in this state until the current is below a threshold. This behavior is different from that of a standard transistor, which requires a continuous current to remain in its “on” state. In addition, the VS-ST180S12P0VPBF can be reset by a negative voltage applied to the gate terminal.

The VS-ST180S12P0VPBF is a rugged and reliable power switching device that is suitable for applications requiring low voltage and current ratings. It is well suited for AC power switching applications, motor control, and large home appliances due to its fast switching speed and low turn-on voltage of 83V DC. The device is also lead-free and RoHS compliant, making it an environmentally friendly option for power switches.
