Diodes - Zener - Arrays are electronic components that consist of multiple Zener diodes integrated into a single package. These devices are primarily used for voltage regulation, offering protection against overvoltage by clamping and stabilizing the voltage to a predefined value. Zener diode arrays are designed to manage excess electrical energy and are commonly found in power supply circuits to provide a stable reference voltage. They are essential in ensuring that sensitive electronics receive constant and safe voltage levels, contributing to the longevity and reliability of electronic systems. Additionally, these arrays can be used in signal processing applications to protect sensitive circuits from electrostatic discharge (ESD).
The main characteristics of Diodes - Zener - Arrays include their ability to absorb transient voltage spikes and regulate multiple lines in a circuit with consistent performance. This multi-diode configuration not only simplifies circuit design by reducing the number of individual components needed but also enhances the overall durability and efficiency of the application. Moreover, their compact form factor makes them invaluable in space-constrained electronics where printed circuit board real estate is at a premium. Prominent manufacturers producing these arrays include ON Semiconductor, Nexperia, Vishay, Microsemi, and STMicroelectronics.
