Explain Zener diode.
Understand the Problem
The question is asking for an explanation of what a Zener diode is, including its function, characteristics, and applications in electronic circuits.
Answer
A Zener diode allows current to flow in both directions and is used for voltage regulation.
A Zener diode is a semiconductor device designed to allow current to flow in both directions, with a special emphasis on reverse direction flow at a specific voltage known as the Zener breakdown voltage. It is commonly used as a voltage reference or voltage regulator in electronic circuits.

A Zener diode is a semiconductor device designed to allow current to flow in both directions, with a special emphasis on reverse direction flow at a specific voltage known as the Zener breakdown voltage. It is commonly used as a voltage reference or voltage regulator in electronic circuits.
More Information
The Zener diode uniquely allows current to flow 'backwards' when the applied voltage exceeds a characteristic threshold known as the Zener voltage. It’s commonly used in power supplies to ensure stable output voltage.
Tips
A common mistake is to assume Zener diodes function like regular diodes in both directions; their specialization is the reverse direction beyond a certain voltage.
