TVS diodes are electronic components capable of suppressing electrical transients of extreme amplitude and short duration. These components are of paramount importance in designing electronic circuits that are more reliable, and operate more smoothly. The 6KA24/4 is a thyristor diode produced by EIC Semiconductors for this purpose. While its main application is the automotive industry, amongst other automotive applications, this component also can be applied to numerous other fields.

The 6KA24/4 is mainly used for its superior protection against electrical transients, under severe automotive loads. It can withstand high currents, withstanding up to 24A, and its reverse breakdown voltage is 4 volts. It also features a very low leakage current, ultimately allowing it to perform in a more reliable manner. Furthermore, its polarity is symbolized by a decisive line, allowing for an intuitive and fast recognition of correct insertion in a circuit.

The working principle of the 6KA24/4 relies on It’s main components, which are the Zener diode, the JFET transistor and a reverse side bipolar transistor. Whenever a positively charged electrical transient is detected that overcomes the 4-volt reverse voltage level, the Zener diode will conduct current, causing the voltage to drop below the breakover voltage of the JFET. This in turn will allow current to flow through the JFET, triggering, when its threshold is surpassed, the bipolar transistor, therefore protecting the other components of the circuit.

The 6KA24/4 is mainly used in the automotive industry due to its electrical noise protection capabilities against loads of high current, such as those sustained by the engine and the electric generator. Additionally, this component is also used in other industrial and commercial applications, such as photovoltaic and solar systems, as well as in the telecommunications and medical fields, and even in railroad, petrol and gas facilities.

Because it is hermetically sealed in a ceramic package, this component can withstand the most arduous conditions of temperature and humidity, providing a high degree of reliability in a wide range of environmental scenarios. Additionally, the 6KA24/4 is RoHS compliant, making it a widely accepted solution.

In conclusion, the 6KA24/4 is a thyristor diode mainly applied to the automotive industry due to its extreme functionality against high currents and transient electrical phenomena. This component can also be useful in multiple other fields of engineering, allowing designers to produce reliable electronic circuits which operate optimally.
