Thyristors - TRIACs

A TRIAC (Triode for Alternating Current) is a three-terminal AC semiconductor switch commonly used in many electronic circuits. They are most often used as efficient switching devices in both AC and DC circuits, as well as for motor control applications. The L4004L3 is an example of a TRIAC.

The L4004L3 is a frequent choice for commercial and industrial circuits due to its ability to be used for a wide variety of applications. The L4004L3 is well suited for AC motor control, AC voltage stabilization, light dimming, and industrial applications.

L4004L3 Application Field and Working Principle

The L4004L3 is well suited for controlling AC switched circuit applications. Due to its extremely low operating power and high switching capability, the L4004L3 is ideal for switching lighting circuits, powering motors, and other power applications. Additionally, the L4004L3 is a very cost-effective solution when compared to other components.

The primary benefit of the L4004L3 is in its ability to handle high currents of up to 125 A, providing it a wide range of applications. The L4004L3 is able to provide a high current switching capability with a low on-resistance of 0.9 Ohms. In addition, the L4004L3 offers a breakover current of 717 mA, which means it can handle large and sudden load changes without becoming damaged.

The operating principle of the L4004L3 heavily relies on the control of current running through the device using gate current. When a certain control current is applied to the gate of the device, it switches on and allows AC current to flow. When the control current is removed from the gate terminal, the device switches off, thus controlling the AC circuit.

The L4004L3 is typically used as a phase control element for controlling AC motors. These devices are used to limit the flow of current to the motor and allow it to run at a variable speed. This allows for more precise control over the speed and torque of the motor, and is useful in applications such as HVAC systems, treadmill motors, and more.

The L4004L3 also provides a low thermal resistance, allowing it to withstand high ambient temperatures and provide reliable operation. This component is reliable, stable, and easy to use, allowing it to be used in various applications such as AC voltage stabilizing and overvoltage protection. The L4004L3 is an ideal choice for many commercial and industrial applications.
