Diodes - Zener - Single

The 3EZ18D10E3/TR8 is a single zener diode, which is a type of diode with a reverse breakdown voltage. This type of diode has a wide range of applications, and it plays an important role in many electronic circuits. In this article, we will discuss the application field and working principle of the 3EZ18D10E3/TR8.

Application Field

As a single zener diode, the 3EZ18D10E3/TR8 can be used for a wide range of applications. The most common use is for voltage regulation, as the diode can be used to regulate the output voltage of a circuit. This is done by connecting the diode in series with the output of the circuit, such that any voltage that is greater than the reverse breakdown voltage of the diode is clamped by the diode. In addition, the 3EZ18D10E3/TR8 can also be used in voltage-dependent switches to control the flow of current in the circuit, as well as for the protection of circuits from overvoltage.

Working Principle

The working principle of the 3EZ18D10E3/TR8 is based on the principle of reverse breakdown. This type of diode has a layer of semiconductor material, typically a junction between p-type and n-type materials, which has a breakdown voltage, or notably a “knee voltage”, that can be exceeded to cause a sudden increase in current. When a voltage greater than the breakdown voltage is applied across the diode, the electric field of the voltage causes electrons to tunnel from the n-type material to the p-type material, creating a situation where current can suddenly flow through the diode. As the current passes though the diode, the voltage across it drops to the point the diode can no longer conduct. This is known as the “knee voltage” and is usually around 8.2 volts. This is the output that the 3EZ18D10E3/TR8 will provide if used for voltage regulation.

The 3EZ18D10E3/TR8 can also be used as a protection element, as it will clamp any voltage that is greater than the breakdown voltage. This protects the circuit by preventing the voltage from rising too high, thus preventing damage to the components in the circuit. In addition, the diode can also be used as a switch, as it will allow current to flow until it reaches the breakdown voltage, at which point it will begin to restrict current flow, allowing it to act as an on/off switch.

Conclusion

In conclusion, the 3EZ18D10E3/TR8 is a type of single zener diode which has a wide range of applications, including voltage regulation, protection of circuits from overvoltage, and for the control of current flow in circuits. The diode\'s working principle is based on the principle of reverse breakdown, where an electric field causes electrons to tunnel from the n-type material to the p-type material, creating a situation where current can suddenly flow through the diode. This type of diode is a valuable component in many electronic circuits, and can be used to great effect in many different applications.
