Z4KE120AHE3/73 application field and working principle

Diodes are semiconductor devices that allow electricity to flow in one direction only. The Z4KE120AHE3/73 is a single Zener diode. It is used in a wide range of applications, including power regulation, protection, clamping, and signal conversions. This article will discuss the application field and working principle of the Z4KE120AHE3/73.

Application Field of the Z4KE120AHE3/73

The Z4KE120AHE3/73 is a high-power rated Zener device with a built-in avalanche diode. This combination of features makes it useful in a wide range of applications. The most common application for Zener diodes is as a voltage regulator for electronic circuits. They can be used to maintain a steady output voltage, even when the input voltage fluctuates. They can also be used to prevent overvoltage or undervoltage in circuits. Another common use for Zener diodes is in wideband frequency converters. In these applications, the Zener diode is used to convert a signal from a low frequency to a higher frequency. Finally, the Z4KE120AHE3/73 can be used as a circuit protector to prevent over-voltage transients. It can be used as both a regular diode and as a Zener diode.

Working Principle of the Z4KE120AHE3/73

The Z4KE120AHE3/73 consists of a junction made up of two N-type and two P-type semiconductors. When a current passes through the diode, the voltage at the junction is equal to the Zener voltage. This is the value of the breakdown voltage of the Zener diode. The Z4KE120AHE3/73 has an avalanche breakdown voltage of 120V, meaning that it will not allow the voltage at its junction to exceed that value. When the voltage rises above the breakdown voltage, the diode will allow a large current to flow, which is known as an avalanche breakdown.

The Z4KE120AHE3/73 also features an enhanced-avalanche diode that provides additional protection against over-voltage conditions. This diode is intended for use in high-frequency applications such as frequency converters, and helps to protect against electrical transients.

Conclusion

The Z4KE120AHE3/73 is a single Zener diode that is used in a wide variety of applications. It is used as a voltage regulator to maintain a steady output voltage, as a wideband frequency converter, and as a protector against over-voltage transients. Its breakdown voltage is 120V and it features an enhanced-avalanche diode for high-frequency applications. By understanding the application field and working principle of the Z4KE120AHE3/73, it is possible to use the device in a wide range of applications.
