T700143004BY

A thyristor is a four-layered, three-terminal semiconductor switching device placed between the power source and an electrical load. It is a type of electrical switching device that can control both the flow of current and reverse current. The Thyristor-SCRs (Silicon Controlled Rectifiers) are used to manage power in many different applications. They are used in applications ranging from consumer electronics, such as dimmers and power supplies, to industrial control, such as UPS systems and motor drives.

T700143004BY is a PNPN power Si-thyristor device that is typically used in phase control circuits, current conduction, and soft-start circuits. Its low off-state leakage current makes it suitable for applications that require low power consumption.

The main application for the T700143004BY is for circuit protection. Its protective features include short circuit, over temperature, and over current. This device also features commutation characteristics that allow it to be used with power switches. Its high surge current and high avalanche capability allow it to be used in high voltage AC/DC and DC/DC applications.

The working principle of the T700143004BY is simple. It consists of two terminals connected with a p–n–n junction. When a current flows through the P–N–N junction, it blocks the flow of current. When a higher voltage is applied to the same P–N–N junction, the current is allowed to flow, thus imposing a temporary path in between the two terminals, as as two-way switch.

In AC control applications, the transistor can be switched on and off using a gate current. The gate current is set to provide a delay between the supply and the load timing. This is known as phase control. In an AC system, the thyristor may be used to regulate the proportion of current flowing through the load, by controlling the firing angle. This process is known as the modulation of waveforms.

The T700143004BY can also be used in DC applications. In this case, a high voltage is required for the switching of the device on, once it is triggered. This high voltage is usually obtained from a transformer. Once the device is switched on, the current flows through the device, performing the same function as an AC system.

The T700143004BY is an extremely versatile switching device and is used in a wide range of applications. Its protective features make it a good choice for circuit protection and its commutation characteristics make it suitable for various AC and DC applications. It is a compact device, and its low off-state leakage current makes it highly suitable for applications that require low power consumption.
