Thyristors - SCRs

Thyristors (also known as silicon-controlled rectifiers, or SCRs) are devices that can control electric current in power electronics. A T72H123544DN is a type of fast-acting, sensitive gate, high-power triac thyristor. This article will discuss the application field and working principle of T72H123544DN.

Application Field

The T72H123544DN is typically used in high-power switching applications, particularly those involving load control in lighting and heating, as well as motor and power control in industrial applications. It is also suitable for applications with difficult EMI conditions, such as cold cathode RGB illumination, in which it can serve as the main switching element. In addition, the T72H123544DN is well-suited for applications requiring a high voltage and high current capability, such as power supplies and UPS systems.

Working Principle

The T72H123544DN thyristor is a four-layer semiconductor device designed to control high currents. It consists of a PNPN structure, and is triggered by a gate current. When the gate current reaches a certain level, it causes the thyristor to switch to the on state, allowing current to flow in both forward and reverse directions.In the off state, the thyristor blocks current flow, and there is no gate current required. When in the on state, the thyristor acts as a low-resistance path between the anode and cathode, allowing current to flow at predetermined levels. The state of the thyristor is governed by the gate current: when the gate current is insufficient or absent, the thyristor remains off; when the gate current is within a certain range, the thyristor switches to the on state. The advantages of using Thyristors include high-speed switching capabilities, low on-state voltage drop and low gate-triggering levels. They are also capable of withstanding high voltages and currents.

Conclusion

The T72H123544DN thyristor is a four-layer semiconductor device that is used for high-power switching applications. It is capable of switching extremely quickly, and is capable of withstanding high voltages and currents. The thyristor is triggered into the on state by a gate current, and remains off when no gate current is present. The thyristor is well-suited for applications in power electronics, such as load control, power supplies and UPS systems.
