Diode, a two-terminal electronic component, is a device that allows electricity to flow in only one direction. It is the basis of almost all electronics and powers modern day technologies. Diode can be broadly classified into three main types; signal, switching and Zener diodes. The BZV55-B47,115 is a specific type of Zener diode, and in this article, we take a look at the application field and working principle of the BZV55-B47,115.

Application Field of BZV55-B47,115

The BZV55-B47,115 is a class of Zener diodes that acts as a voltage regulator and is used in many electronic circuits. With its ultra-precise breakdown voltage of 11.5 volts, the BZV55-B47,115 can regulate a voltage of 12 volts to a precise 11.5 volts. This makes it ideal for various applications such as automotive, industrial, communications, and consumer electronics. Moreover, it can also be used as a transient overvoltage protection device in various applications. It is available in a compact plastic package with two pins spaced at 2.5 mm.

Working Principle of BZV55-B47,115

A Zener diode allows reverse current to flow under certain conditions. This is known as “Zener Breakdown” and is the working principle of Zener diodes. When a Zener diode is connected in a circuit, a voltage drop is created across the diode. The magnitude of this voltage depends on the breakdown voltage rating of the diode. In the specific case of the BZV55-B47,115, this voltage drops is 11.5 volts. This voltage drop stays constant irrespective of any fluctuations in the input voltage.

To understand the working of Zener diodes more, let’s consider a simple Zener diode circuit. In this circuit, a Zener diode is connected in series with a resistor and a power source. When the source voltage is above the breakdown voltage of the diode, the diode is reverse biased and its resistance is infinite, meaning that the current through it is 0. When the source voltage is reduced below the breakdown voltage of the diode, the diode enters Zener breakdown and a reverse current starts to flow through it, allowing it to regulate the voltage.

Conclusion

In conclusion, BZV55-B47,115 is a type of Zener diode that is mainly used to regulate the input voltage of a system to a precise 11.5 volts. It can be used in various applications, such as automotive, industrial, communications, and consumer electronics, and can also be used as a transient overvoltage protection device. Its working principle is based on Zener breakdown, in which a reverse current is allowed to flow through the diode when the source voltage is reduced below the breakdown voltage of the diode.
