B654SE-2T

Thyristors – SCRs – Modules

The B654SE-2T is a part of a family of modular semiconductor control devices, specifically a Thyristor SCR (Silicon Controlled Rectifier). They are used when a high efficiency, low power requirement or higher voltage is needed. The B654SE-2T is particularly suitable for use in applications requiring up to 40 amp output current, up to 800 volts and on/off control.

Application Field

The B654SE-2T has a wealth of applications where it can be used as a control element. These include; heating elements, electric motor/power electronics, welding systems, solenoids, electric motors and lighting systems. In addition to this, the B654SE-2T can be used in applications such as electrical appliances and industrial process controls.

The B654SE-2T is commonly used in lighting systems and industry where higher voltages and currents are present. In this capacity the B654SE-2T can be used to switch between various operating modes, enabling a user to control specific elements. As an example, in lighting systems, the B654SE-2T can be used to switch between different brightness settings by controlling the current running through the module.

Working Principle

A Thyristor SCR is basically a fast-switching device that is controlled by an input signal. It is made up of four semiconductor layers and two junctions. The Thyristor SCR works by using the current flowing through the Gate terminal to start or to continue the flow of current in the main terminals. This switching characteristic makes it ideal for use in applications that require fast response times.

When a gate signal is applied to the B654SE-2T, it triggers a rapid switching action between conducting (on) and non-conducting (off) states. This switching action is triggered by the voltage difference between the Gate and Anode terminals and the current flowing through these terminals. The Anode and Cathode terminals control the current limit while the Gate terminal controls the flow of the current.

The B654SE-2T is typically used in applications that require higher voltage and current because of its medium speed switching capability. This kind of device provides great usage for repetitive switching operations, which can be beneficial in many applications.

Conclusion

The B654SE-2T Thyristor SCR is a field-effect transistor (FET) device that can provide an excellent cost-performance ratio. It is ideal for applications that require higher voltage, current and switching speed. The B654SE-2T offers an efficient and durable solution for applications where higher control is needed.
