Diodes - Zener - Single - BZX84-C24,215 Application Field and Working Principle

BZX84-C24,215 is a Zener diode, which is specially designed to function as a voltage regulator within an electrical circuit. Zener diodes allow current in either direction, but only when the voltage exceeds the breakdown voltage of the diode, also known as the Zener voltage. This ensures that a certain preset voltage is maintained when electrical power is supplied to the circuit, and the circuit that is being regulated is said to be in a regulated state. By controlling the breakdown voltage, it becomes possible to apply different voltage outputs to a wide variety of devices, making Zener diodes highly versatile.

Application Field

The BZX84-C24,215 Zener diode is mostly known for its application in regulating the input and output voltages of solid-state devices, such as microcontrollers, flip-flops/latches, and power transistors. It also has useful applications in controlling voltage levels in analogue circuits. In an increasing number of electrical circuits, it is quite common to find the BZX84-C24,215 Zener diode. It can be used in a variety of different parts of the circuit where an adjustable or stable voltage is needed, depending on the requirements of the circuit.

Working Principle

The working principle behind all Zener diodes is that when the voltage provided to the diode exceeds the breakdown voltage, a small amount of current, known as the ‘zap’, is allowed to travel in the opposite direction. This zap is small enough that it does not damage any of the elements in the circuit, but it is enough to ensure that the voltage level is maintained. Thus, the circuit is said to be in a regulated state. By controlling the zap, it becomes possible to adjust the voltage level, thus allowing the regulator to provide different voltages as necessary.

The BZX84-C24,215 Zener diode also utilizes two kinds of junctions, the P-type and the N-type. The P-type junction is placed near the anode of the diode, and it consists of a thin sheet of heavily doped silicon. This sheet contains a number of holes in it, which allows the current to flow through freely. The N-type junction, on the other hand, is located near the cathode, and is made up of a very thin sheet of lightly doped silicon. This sheet also has a number of holes in it, which help to capture any excess current that may have traveled in the reverse direction.

These two junctions, when combined with the Zener voltage, are what make the BZX84-C24,215 Zener diode so useful for voltage regulating. The P-type junction is responsible for allowing the current to flow in one direction, while the N-type junction helps to block any current flowing in the opposite direction. Thus, the BZX84-C24,215 Zener diode is able to maintain a constant voltage in the circuit, regardless of fluctuations in the input voltage level.

Conclusion

The BZX84-C24,215 Zener diode is a very useful device for controlling the voltage levels in a variety of electrical circuits. It works by allowing a small ‘zap’ of current when the voltage level reaches the Zener voltage, thus keeping the voltage within a preset range. The diode utilizes two junctions, the P-type and the N-type, which help to regulate the flow of current in the circuit. The versatility of the BZX84-C24,215 has made it a very popular choice for a wide variety of applications, from power transistors to microcontrollers.
