Zener diodes are primarily used as voltage references and current limiters.

1. Voltage References: Zener diodes are commonly used as voltage references in many circuits. They have a unique property that allows them to maintain a constant voltage across their terminals, regardless of the current flowing through them. This makes them ideal for use as voltage references.

2. Current Limiters: Zener diodes can also be used as current limiters. When used in this way, they help to prevent excessive current from flowing through a circuit. This can be particularly useful in protecting sensitive components from damage.

Zener diodes are not typically used as variable resistors or power distributors. Variable resistors are components that are designed to adjust the resistance within a circuit, and power distributors are used to distribute power throughout a circuit. These are functions that are outside the typical use of a Zener diode.
