Thyristors are a major branch of electrical components that are widely used in power control and power conversion sections. The most commonly used type of thyristor is the silicon-controlled rectifier (“SCR”). The S401E is an SCR device designed specifically for high power applications.

The S401E has a low on-state voltage drop ranging from 1.5 to 2 volts, providing maximum visibility during operation which makes it a great choice for more efficient power control systems. The S401E is able to operate at high temperatures of up to 800°C, withstanding environments resistant to higher temperatures and pressures. It also features a long lifetime expectancy of up to 25,000 hours, ensuring dependable performance.

The S401E has a wide range of applications due to its powerful structure. It is used in circuitry that requires power transmission and digital circuits, such as in control of electric motors, resistive loads, digital circuits for measuring and switching, rectifiers for bridge circuits, flyback and other inverters, and many other devices. Its high performance in multiple applications makes it a popular choice for engineers and technicians.

The working principle of the S401E relies on the integrated rectifier circuit. The rectifier comprises two thyristors connected in series, with one electrode of each being connected to the other electrode. The other electrode is connected to the control unit, which functions as the output voltage source. Whenever the control voltage rises, one of the thyristors is triggered and a current path is created. When the current path is established, a current will flow through the control unit, providing a path for the control voltage to flow through.

When the control voltage is removed, the current path is terminated and the thyristors are once again open. This sequence can be repeated as long as the control voltage is continuously provided to the S401E. The power that is allowed to flow through the thyristors is regulated, monitored, and controlled by the control unit.

The S401E is designed to enable engineers and technicians to easily control currents in power devices. Its ability to provide consistent voltage, along with high current switching capabilities and long lifetime expectancy make it a perfect choice for applications that require reliable operation. In addition, due to its efficient operation and low cost, it is a great way to save energy and improve performance.
