A single Zener diode, such as BZV90-C8V2, is a semiconductor device that is specifically designed to permit the flow of electricity in one direction - from anode to cathode - but not in the opposite direction. The Zener diode\'s characteristics are determined by its P-N junction and breakdown voltage. The diode has a reverse breakdown voltage rating of 8 volts, which means that it will only permit current to flow when the voltage across it exceeds 8 volts. The Zener diode is also used to regulate the applied voltage.

The advantage of using a single Zener diode is that it can provide protection against voltage spikes, allowing the device to keep operating even if the voltage momentarily exceeds the maximum that it is designed for. This is because the Zener diode will start operating when the voltage across it reaches its breakdown voltage, thus limiting the voltage. The advantage of using a single Zener diode is that it is inexpensive, simple to use, and can be used in circuits with a wide range of voltage values.

The application field of single Zener diodes is quite diverse. They are most commonly used in power supply circuits and low-voltage electronic circuits for protection against excess voltage. They can also be used in voltage regulation circuits, such as current-limiting, voltage-regulating circuits, AC-DC converters, and DC-DC converters. Single Zener diodes are also used to protect sensitive components from high voltage.

Single Zener diodes are also used in radio and television equipment, as they can be used to prevent the damaging effects of parabolic reflections. The most common application is to protect the receiver\'s input stage from voltage overloads. Single Zener diodes can also be used in voltage multipliers, which are used in many applications, such as rectified AC power supplies, ripple filters, and signal dividers.

The working principle of a single Zener diode is based on the properties of its P-N junction. When a voltage is applied to the diode, the P-N junction will form a depletion region, resulting in a built-in electric field. This electric field creates a forward voltage, known as the breakdown voltage, which is the maximum level at which current can start to flow in the reverse direction. At voltages above the breakdown voltage, a large current will flow through the diode and the voltage across it will be clamped at the breakdown voltage.

Single Zener diodes are very important components in the design of electronic circuits. They offer simple and economical solutions for protection of sensitive components from high voltages and for voltage regulation. Single Zener diodes are available in different voltage values, and are relatively inexpensive and easy to use.
