For a Zener diode

Question

For a Zener diode (A) both p and n regions are heavily doped (B) p region is heavily doped but n region is lightly doped (C) n region is heavily doped but p region is lightly doped (D) both p and n regions are lightly doped

Tardigrade Admin · Accepted Answer

Both p and n are heavily doped, so that breakdown occurs easily.

Q. For a Zener diode

both p and n regions are heavily doped

p region is heavily doped but n region is lightly doped

n region is heavily doped but p region is lightly doped

both p and n regions are lightly doped

depletion region is very thick

Both $p$ and $n$ are heavily doped, so that breakdown occurs easily.
