L2004L5

Thyristors are solid-state semiconductor devices with three or more terminals which control current flow through the device. One of the most common types of Thyristors is the TRIAC (Triode for Alternating Current). It is a three-terminal device that is designed to control AC current. Generally, the TRIAC is used in applications where power control is required, such as light dimmers, electronic motor speed control, and AC switching. It is also capable of controlling a wide range of currents, from milliamps to several hundred amperes.

The L2004L5 TRIAC is a four-terminal device based on the standard three-terminal design. It is used in AC switching applications, such as light dimmers and electronic motor speed control. Its main function is to control AC current without the need for a rectifier or transformer. It has four terminals, gate, main terminal 1, main terminal 2, and auxiliary terminal 2. The gate terminal is used to control the TRIAC’s switching state. When the voltage at the gate is high enough, the TRIAC is triggered, allowing current to flow through it. When the gate voltage is low, the TRIAC is off, preventing current flow.

The L2004L5 TRIAC is a sensitive gate device, meaning it is triggered at very low gate voltages. It can be easily triggered with a basic voltage signal, such as 4V or 5V. This makes the L2004L5 a great choice for applications that require low-power switching. It can also be used in applications that require high-current switching, such as AC motors.

The working principle of the L2004L5 TRIAC is fairly simple. When a voltage signal is applied to the gate terminal, the TRIAC is triggered and turns on. When the signal is removed, the TRIAC turns off, preventing current from flowing. This is known as “zero-cross” switching, as the signal must cross a threshold voltage to turn the TRIAC on or off. The L2004L5 is designed to have a breakdown voltage of 500V, allowing it to switch high voltage AC currents.

The L2004L5 TRIAC has a wide range of applications, ranging from light dimmers and motor speed control to AC switching and power control. It is an excellent choice for low-voltage applications and can also be used in high-current applications. Its sensitive gate design allows it to be triggered with simple voltage signals, making it a great choice for low-power switching applications. It is a reliable and efficient device that can handle a wide range of current and is perfect for a variety of applications.
