Thyristors – SCRs are solid-state, self-controlled rectifying devices mainly used for triggering and controlling voltages and currents. The S8025R is a popular SCR from a family of solid state relays. It is a unidirectional thyristor switch that is designed to switch AC loads with high efficiency at a predetermined voltage level or pulse. By controlling the voltage and current, S8025R can be used to switch a variety of loads in a variety of applications. This article details the application field and working principle of the S8025R.

Application Field of S8025R:

The application areas of the S8025R are vast and can be used in any environment that requires controlling and/or switching of AC loads. Some of the common applications include motor/lighting control, heating/cooling control, power supply control, battery charging and discharging control, and AC line control. The S8025R can be used for a variety of control scenarios but its primary purpose is for controlling AC loads.

The physical build of the S8025R is designed to withstand high temperature environments, up to +125°C, with excellent reliability. Additionally, it can be used in environments with high voltage up to +660V and low current up to 1.1A. This makes it an ideal choice for many applications.

Working Principle of S8025R:

The S8025R is composed of two parts: the transistor and the diode. The transistor works to control the voltage and current, while the diode works to rectify AC current and convert it to a form that can be used by the SCR. The transistor is activated when a voltage is applied to the gate terminal, allowing the transistor to conduct current. The voltage is then turned off and the transistor turns off, creating a break in the electrical circuit. When the voltage is then reapplied, the transistor will conduct again, allowing the current to flow.

The SCR is able to switch AC loads by controlling the voltage and current. When the voltage reaches a predetermined level, the SCR will trigger, switching the AC load On/Off. With proper control and programming, the SCR can be used to switch AC loads in a variety of applications. Additionally, because the SCR is a solid state device, it operates with high efficiency and accuracy.

Conclusion:

The S8025R is a popular SCR from a family of solid state relays. It is designed to switch AC loads with high efficiency at a predetermined voltage level or pulse. It is essentially composed of two parts: the transistor and the diode. The transistor works to control the voltage and current, while the diode works to rectify AC current and convert it to a form that can be used by the SCR. With proper control and programming, the SCR can be used to switch AC loads in a variety of applications. Its robust physical design allows it to work in environments with high temperature, up to +125°C, high voltage up to +660V and low current up to 1.1A.
