Thyristors are semiconductor devices largely used for controlling electric power in AC applications. Among the various types of thyristors, TRIACs (triode AC switch) in particular find a wide-range of applications due to the popularity of AC devices. T405-800H is a type of two-way (bipolar) TRIACs, which uses the gate terminal to control the bi-directional current.

T405-800H can be used to switch electric power of up to 400 volts in AC circuits. With a power dissipation rate of 800 watts, this component is particularly suitable for applications that require repeated operations in a short period. Operating at high speeds, T405-800H can be operated astronomically, or from an external signal source such as a timer or a control panel.

The main working principle of T405-800H is to control the bi-directional electric current by using a gate terminal. Once a small current is applied to the gate terminal, the two thyristors are triggered and a bridge can be formed across the two terminals, allowing current and voltage to pass through the device. This mechanism is used to control the magnitude of the current by blocking or allowing a certain amount of voltage through the gates.

While the device is used in many different applications, it is fairly easy to understand and use. The main applications of this device include motor control and speed regulation, light dimming and illumination, and power switching for heaters, fans and resistive heating elements. Furthermore, this device is also used for AC switching in remote control units and power-on circuit resetting in various electronic equipment.

In addition, this device is also commonly used for AC interface circuits and single-phase motor control circuits. Since it is a bi-directional switch, it can be used to control the bi-directional flow of current by applying a small current at the gate terminal. This makes it suitable for bidirectional switching and operating functions in AC circuits.

To ensure the safety of T405-800H, a fuse should be used to protect it against overload. With the right fuse in place, the device will be better protected against current overloads and voltage surges. Additionally, it is important to ensure that the device is meant for the application it is used for and the right ratings are selected for the device.

T405-800H is a great example of a TRIACs device that can be used for various AC applications. It provides reliable switching for AC circuits and can effectively be used for motor control, dimming and power switching functions. With its efficient gate-controlling principle and high ratings, it can greatly simplify the design of AC circuits.
