What is Zener Diode Array?

A Zener Diode Array is a collection of Zener diodes arranged in a single package or module, typically designed for use in voltage regulation or surge protection applications. Zener diodes are semiconductor devices that allow current to flow in the reverse direction once a specific reverse voltage, known as the Zener voltage, is reached. In a Zener diode array, multiple diodes are often used together to handle different voltage levels, improve reliability, or simplify circuit design.

These arrays can be particularly useful in scenarios where:

1. Overvoltage Protection: They protect circuits from voltage spikes by clamping the voltage to a specific level.
2. Regulation: They can regulate voltage across a range of different input conditions.
3. Space Efficiency: By integrating multiple Zener diodes into a single component, they save space compared to using individual diodes.
4. Load Balancing: In some cases, arrays are designed to balance the load across multiple diodes to prevent overheating and improve overall lifespan.

Zener diode arrays are commonly used in power supplies, communication equipment, and other electronic systems that require stable voltage regulation or protection.
