Breakdown of the Problem

In this question, we are asked to identify the operational mode of a Zener diode. The Zener diode is typically used in voltage regulation applications and has distinct operational characteristics.

Relevant Concepts

A Zener diode can operate in various modes:

1. Forward Bias - When the diode allows current to flow in the forward direction.
2. Reverse Bias (Zener Breakdown) - The diode operates in reverse bias, where it maintains a constant voltage across it when the reverse voltage exceeds a certain threshold known as the Zener voltage.
3. Cutoff - Where the diode is not conducting at all, typically when the reverse voltage is below the Zener breakdown voltage.
4. Saturation - More commonly related to transistors, and less applicable to Zener diodes.

Analysis and Detail

• Forward Bias: In this mode, the Zener diode conducts current, but it’s more characteristic of regular diodes.
• Zener Breakdown: This is the primary operational mode of a Zener diode, allowing it to regulate voltage effectively by maintaining a stable output voltage despite variations in the input voltage or load.
• Cutoff: Occurs when the reverse voltage is less than the breakdown voltage, thus the diode does not conduct.
• Saturation: This term is not typically used to describe Zener diode operation.

Verify and Summarize

Given the characteristics of the Zener diode, it primarily operates in reverse bias condition, specifically in the Zener breakdown region when it is utilized for voltage regulation.

Final Answer

The Zener diode is designed to operate in Zener breakdown.
