Thyristors – TRIACs are solid state semiconductor devices that can be used to control power in AC circuits. TRIAC stands for “Triode for Alternating Current,” and refers to the fact that it contains three components: two transistors, two diodes, and an active element. The L0109NE is a common type of TRIAC used to switch and control AC power.

The L0109NE is a widely used TRIAC due to its numerous applications and its relatively low cost. It is used in a variety of tasks, including motor control, AC heating, lighting control and similar AC power applications. It can also be used in rectifier and inverter circuits.

The L0109NE is a sensitive gate TRIAC, meaning that it is triggered by a small electrical signal at the gate. It has a maximum peak repetitive current rating of 8A, and a maximum on-state voltage of 800V. When used in a rectifier circuit, the breakdown voltage is 250V.

In its simplest form, a TRIAC is just a switch that can be opened and closed with one control signal. It is important to note, however, that unlike other switching circuits, which open and close only at certain points in the cycle of the alternating current, a TRIAC will close the circuit at any point in the AC cycle. This makes the TRIAC much more versatile and useful for a variety of power control applications.

The working principle of the L0109NE TRIAC can be explained as follows. When the gate of the device is activated with an external control signal, electrons are released and move into the gap between the two electrodes of the transistor, forming a conductive path. This path allows current to travel through the device and the circuit is closed. When the control signal is removed, the current can no longer pass through the gap and the circuit is opened.

The L0109NE is a widely used TRIAC in AC circuits due to its numerous applications and its relatively low cost. Its working principle is straightforward and easy to understand. With its ability to be switched and controlled by a small electrical signal, it is a great choice for many AC power control applications.
