Zener diodes are a type of diode designed and manufactured to operate in the reverse-bias breakdown region. When a reverse bias voltage is applied to a standard diode, a large current flows, but this current is limited to a safe level in Zener diodes. PZU18B2A,115 is a type of Zener diode, widely used for voltage regulation and providing voltage overshoot protection.

The PZU18B2A,115 Zener diode has a few key features and specifications. The maximum reverse bias is 18V, with a maximum power dissipation of 200mW. The maximum reverse current is 6mA, while the maximum dynamic resistance is 275 ohms. This diode also features a Do-17 package, making it suitable for most applications.

The PZU18B2A,115 Zener diode is typically used in applications such as power supply design, power conditioning, voltage regulation, and overvoltage protection. It can be used to provide protection against transients or surges in power or voltage. For example, if a transient increases the input voltage, the Zener diode can limit the surge by conducting the excess voltage, reducing the total power dissipated. The diode also removes any AC components from the output DC voltage, creating a stable and consistent voltage for other circuitry.

The working principle of the PZU18B2A,115 is based on the reverse breakdown of the diode. When a reverse bias voltage is applied to the diode, the electric field across the junction increases. This electric field will eventually reach a point where the junction breaks down, allowing a large current to flow through the diode. This current is limited to a safe level by the Zener diode\'s built-in stabilizing element. This allows for a consistent, stabilized voltage to be output to the other circuitry.

The PZU18B2A,115 Zener diode is a simple, yet effective tool for taking advantage of the breakdown characteristics of the diodes. Its key features, including its wide reverse bias range, low power dissipation, and enhanced stability make it a great option for voltage regulation applications. Additionally, its Do17 package makes it suitable for a large number of applications across industries.
