Thyristors - TRIACs

L6004L3 Application Field and Working Principle

Thyristors are a type of semiconductor device used as a switch, rectifier, or voltage or current regulator. When triggered, thyristors switch on, allowing current to flow in either direction between the gate and the anode, and remain in that state until triggered off. The L6004L3 is a TRIAC, a special type of thyristor designed to switch high voltages and currents on and off. This article examines the application field and working principle of the L6004L3.

Applications Field

The L6004L3 is a high-power TRIAC with a rated current of 400 A at a rated voltage of 600 V. This makes it suitable for use in applications such as welding, CNC applications, high-power heating, printing, woodworking machinery, HVAC, and more. It is highly resistant to temperature, vibration, and thermal shock, making it ideal for high-reliability industrial applications.

Working Principle

The L6004L3 is a three-terminal device with a control terminal (gate), a main terminal 1 (MT1) and a main terminal 2 (MT2). When a voltage is applied to MT1 and MT2, electrons are injected into the gate terminal and the thyristor begins to conduct. By controlling the amount of current flowing through the gate, the L6004L3 is able to switch the main current on and off, making it an ideal choice for applications in which fast switching times are required.

The L6004L3 features various other characteristics that make it particularly well suited for use in industrial and commercial applications. The device features robust dielectric strength of 600 V, low voltage rating of 100 V, and a wide operating temperature range from -40°C to 125°C. Additionally, the device has a high surge current capability of 16 kA, making it suitable for harsh industrial environments.

The L6004L3 is a simple, reliable device with a range of applications. Its high current, high voltage, and high surge capabilities make it ideal for a wide variety of industrial and commercial applications. Its low voltage rating and wide operating temperature range guarantee a long service life in a range of harsh environments.
