Diodes are semiconductor components in electrical and electronic circuits with the ability to control the direction of flow of electric current. The Zener diode is a type of diode that allows current to flow in either direction when forward biased, but can also be reverse biased to operate as a voltage regulator, or to make an electrical conduction path when the reverse voltage reach a certain threshold. One example of a Zener diode is BZX84C5V1LFHT116.

Application Fields

BZX84C5V1LFHT116 is primarily used as a voltage regulator, providing a reference voltage that is constant despite fluctuations in line voltage or load conditions. Typical applications of Zener diodes typically include their use as reference sources, clamping devices, surge suppressors and voltage regulator circuits.

In voltage regulator circuits, the Zener diode is often used as a way to limit the voltage applied to sensitive devices. This is because the diode\'s behavior forms a “clamping” effect across the circuit whose voltage does not exceed the Zener voltage. In other words, it prevents the voltage from climbing any higher than the Zener voltage.

In reference source applications, the Zener diode can act as a source for a bias voltage which is used to stabilize the operating point of an analog circuit. The diode is used in conjunction with a power supply, a resistance, and often a buffer amplifier.

Surge suppressors are also used to limit the voltage applied to a circuit. The BZX84C5V1LFHT116 Zener diode, in particular, is used in a circuit that clamps sharp electrical spikes and helps to protect transistors and integrated circuits from over-voltage damage.

Working Principle

The working principle of a Zener diode is the same as a conventional diode. Conventional diodes are unidirectional, meaning they let current flow through the anode to cathode when forward-biased, and prevent current from flowing through the anode to cathode when reverse-biased. Zener diodes, on the other hand, allow current to flow in both directions when forward-biased and also limit current flowing from cathode to anode when reverse-biased.

Zener diodes rely on their reverse breakdown voltage (Vz) to regulate current flow. Reverse breakdown voltage is the voltage where the Zener diode “breaks down” and begins to let current flow. This is typically 5V–12V, but can be adjusted by adding a resistance in series with the Zener diode. Once the reverse breakdown voltage is reached, the Zener diode begins to conduct current in the reverse direction, limiting it to the value of Vz.

The BZX84C5V1LFHT116 Zener diode has a reverse breakdown voltage of 5V and can limit the voltage applied to circuits, thereby preventing potential damage due to over-voltage. This makes it an ideal choice for voltage regulator circuits and other reference source applications, as well as surge suppressors.

Conclusion

The BZX84C5V1LFHT116 Zener diode is a type of semiconductor component with the ability to control the direction of electric current in a circuit. It works by allowing current to flow in either direction when forward-biased and limiting current flowing from cathode to anode when reverse-biased. The reverse breakdown voltage of the BZX84C5V1LFHT116 is 5V, making it an ideal choice for applications that require a constant voltage reference, such as voltage regulator circuits, reference source circuits, and surge suppressors.
