Question

Differences between zener diode and pn junction diode in geeksforgeeks

Answer 1

Difference Between PN Junction &Zener Diode. The major difference between PN junction and the Zener diode is that the PN junction diodeallows current to pass only in theforward direction, whereas the Zener diode allows the current to flow both in the forward and the reversed direction.

Answer 2

Diode is the simplest semiconductor element, which has one PN-connection and two terminals. It is a passive element because the current flows in one direction. The Zener diode, on the contrary, allows flowing of the reverse current.
