Working Principle

The working principle of the L2004F61 is a combination of semiconductor elements and electrical resistive elements based around the IGBT process. The device uses three resistive elements, called the gate, the main current carrying channel and the anti-parallel channel. The gate forms an element in which an external electric field is established by the thyristor drive circuitry.

The main current carrying channel is formed by connecting a thyristor between an anode and a cathode in series with the gate. By connecting a gate voltage exceeding the breakover voltage, the thyristor becomes highly conductive, allowing a current to flow through the channel. To turn off the device, the gate voltage must go below the breakover voltage.

The anti-parallel channel is established by connecting the anode to the cathode in an opposing voltage and current circuit. When a positive potential is applied to the gate, the voltage across the anti-parallel channel, also known as the leakage current, becomes high enough to turn the thyristor off. This ensures an effective overcurrent protection of the circuit and to reduce the power consumption.

In conclusion, the L2004F61 is an essential thyristor with versatile features and excellent performance. Its combination of a resistive gate, the main current-carrying channel, and the anti-parallel channel allows for versatile and efficient control. This device has become a standard for reliable and precise control in a wide range of applications.
