Diodes are electronic components that conduct electricity in one direction only, and the Zener type is capable of enabling current flow in the opposite direction when a certain voltage level is reached. The BZX284-C Series single Zener diode is a common part that can be used in a variety of applications. In this article, we will discuss the application fields and working principle of the BZX284-C18/115 diode.

The BZX284-C18/115 is a single Zener diode that has a maximum forward voltage drop of 1.57V at a forward current of 18mA. It has a maximum reverse voltage of 20V and a power dissipation of 250mW. This diode is specifically designed to be used in automotive applications and other space-constrained applications.

This type of diode is commonly used in a variety of applications, such as protection circuits, polarity protection circuits, overvoltage protection, and power supplies. It can also be used in voltage stabilization and as a voltage reference. Protection circuits are designed to protect the device from overvoltage and polarity reversal, while polarity protection circuits are designed to ensure that the correct polarity is applied to the device. Overvoltage protection is designed to protect the device from overvoltage conditions by shunt the current away from the device, and power supplies use the diode to regulate and stabilize the voltage levels.

The working principle of the BZX284-C18/115 diode is quite simple. When the forward voltage is applied, the diode behaves like a normal rectifier, allowing the current to flow in only one direction. When the voltage reaches the Zener voltage, the diode starts to act like a Zener diode, allowing the current to flow in both directions. This process is known as “reverse breakdown”, and it helps to protect the device from overvoltage.

The Zener diode also acts as a voltage reference as well as a voltage stabilizer. When voltage is applied to the diode, it will allow the current to flow in both directions, but it will provide a fixed voltage level, thus stabilizing the output voltage.

The BZX284-C18/115 is a versatile single Zener diode, making it a popular choice for a variety of applications. It can be used to provide protection, voltage stabilization and voltage reference, making it a valuable component for many applications. It is also a cost-effective diode, so it is often preferred over other types of diodes for automotive applications, as well as for other space-constrained applications.
