- Zener diodes are heavily doped than ordinary diodes.
- Zener diodes have an extra thin depletion region.
- It is a silicon semiconductor device that permits current to flow in either a forward or reverse direction.
EXPLANATION:
- Zener diodes allow current to flow in either a forward or reverse direction.
- The junction in the Zener diode breaks down when potential reaches the Zener Voltage and the voltage across the terminals of a Zener diode is reversed.
- This is why it is also known as a breakdown diode.
- This makes the current flow in the reverse direction also.
- So the correct answer is option 3.
