Thyristors - SCRs (T720043504DN) are components used in many industries, including automotive, aviation, and medical. SCRs are current operated semiconductor devices used to control the flow of electricity by either turning on or turning off. SCRs are designed to either be normally off or normally on, depending on the application for which they are used.

When an SCR is in the ‘off’ state, no current is allowed to pass through and the SCR looks like an open circuit. When a current is applied to the gate terminal and the voltage exceeds a certain threshold value known as the ‘holding voltage’, the SCR switches on, allowing current to flow through the SCR and allowing it to act as a closed circuit. The amount of current allowed to pass through depends on the amperage rating of the SCR.

The T720043504DN device belongs to a family of SCRs known as ‘three-terminal SCRs’, which have three distinct terminals: the anode, cathode and gate terminal. These three terminals provide a much higher current rating and amperage than other SCRs and are typically used for high voltage, high current applications. The T720043504DN is a 16 A thyristor, meaning it can handle up to 16 amps of current across its two terminals.

The T720043504DN is used in applications that require switching large amounts of power, such as motor speed control, power factor correction, AC/DC power switching and DC/AC inverters. This device is designed to be controlled by a low-power signal or direct current, which requires only a minimum amount of power to operate. The on/off switching action of the T720043504DN is ideal for applications such as motor control, where the power needs to be adjusted quickly and accurately. This device can also be used in circuit breakers to quickly and safely shut off electrical power when needed.

Another application for the T720043504DN is in the current sensing field. This device can be used to detect the presence of current from a circuit, allowing power to be supplied if the current is low, or cut if the current is too high. This application requires the SCR to be connected in parallel with the circuit, which will allow the SCR to detect the current without it affecting the circuit’s voltage or amperage.

In summary, the T720043504DN is a 16 A three terminal SCR devices that is used in applications such as motor speed control, power factor correction, AC/DC power switching and DC/AC inverters. It is also used in current sensing applications to detect the presence of current without affecting the power supply. In addition, this device can be used in circuit breakers to quickly and safely shut off electrical power when needed.
