The OT380/116 is a member of a class of devices known as thyristors or TRIACs which have a distinctive ability to control electric current. Thyristors are primarily used in applications requiring solid state switching, such as electric control systems, where they are used to control a wide variety of electrical loads. They are also used in a wide range of electronic circuits, in particular, those involving electric motor drives, AC power control, and power rectifiers.

Thyristors, or TRIACs, are a type of electric component made up of several layers of semiconductor materials sandwiched between two electrodes. They work on the principle of two-way current flow, by allowing current to go in both directions in the circuit. Conventional diodes, on the other hand, allow current to flow in only one direction.

The OT380/116 is a low-voltage, medium-power device. It features a breakdown voltage rating of 400V, making it well-suited to low-voltage AC power control applications. It also offers a rated gate trigger current of 2A, and a rated holding current of 25A. The OT380/116 is also designed to be very efficient and is capable of dissipating as little as 1.2W of power. This makes it well-suited to many power control applications, such as AC thyristor control systems.

The OT380/116 works on the principle of thyristor turn-on, which is the process by which current from the gate is allowed to flow. This begins by applying a negative pulse (to the gate) which increases the forward breakover voltage of the device and allows current to flow. Once the current is flowing, the gate voltage must be maintained to ensure continuous current flow. Once the gate voltage is removed, the current flow is halted and the device is turned off.

The OT380/116 is typically used in a wide range of AC power control applications, including lighting control, motor speed control, overheating protection, fan control, and more. It is also used in rectifier circuits, and can be used to switch AC or DC power. It is also useful for applications where AC or DC power needs to be switched quickly, such as in electric stoves and ovens. Additionally, it can be used in applications requiring long-term timing control, such as in automatic window blinds or irrigation systems.

The OT380/116 is well-suited to controlling medium-power loads efficiently, due to its low-voltage rating and its efficient power dissipation. It is a reliable and cost-effective device, making it a popular choice for many power control applications. It is also relatively easy to work with and can be implemented in a variety of projects.
