Thyristors, or silicon controlled rectifiers, are a class of switching devices used in a wide variety of electrical appliances and circuits. A thyristor is a semiconductor device that can be triggered into an on or off state. The TPA120RL is one such thyristor. Its application field and working principle are discussed in this article.

Application Field

The TPA120RL 15A ultra-fast thyristor is suitable for a wide variety of applications. Its most common application is as an energy saving light dimmer. As the name implies, this device dims (or dimmed) light to the desired level. It works as a solid state relay, where it is used to control a light circuit with very low power consumption. It can also be used to switch high currents, such as power supplies, AC motors, and motor drives.

This thyristor is also used in industrial electronic controls such as circuit breakers and circuit protection. It is also used in medical equipment, automotive applications, and as an industrial high-speed switch. The TPA120RL is a robust device that is designed to be highly reliable and long lasting.

Working Principle

The TPA120RL is a two-terminal thyristor. It is composed of three main components - the anode, cathode, and gate. When a positive voltage is applied to the gate, the thyristor will be triggered by a current flow from the anode to the cathode. This is known as the “triode” state, where the current flow in the thyristor is in the same direction.

In the “reverse” state, the situation is reversed. When a negative voltage is applied to the gate, the thyristor will be triggered into a current flow from the cathode to the anode. This is known as a “reverse” state, where the current flow in the thyristor is in the opposite direction to the triode state.

The TPA120RL is also designed with a “safe operating area” in mind, which limits the amount of current that can pass through the device at any given time. This ensures that no damage is caused to the device or its components if the current is too high.

The thyristor can also be used in a variety of ways, such as a temperature control device, where the current is limited to a certain level according to the temperature. The thyristor is also used in surge protection, where it can limit the amount of current passing through the system at any given time.

Conclusion

The TPA120RL 15A ultra-fast thyristor is a versatile device with a wide variety of applications. It is used for circuit protection, controlling current flow, and temperature control. By triggering it in both forward and reverse directions, the TPA120RL is used to switch high currents in a safe and reliable manner.
