AREVERSE breakdown region (used for voltage reference)
BJust on
CForward only
DRandom
Answer & Solution
Correct answer: A. REVERSE breakdown region (used for voltage reference)
**Zener:** heavily doped p-n junction
sharp breakdown at specified V_Z (typically 3-50 V).
Operated in reverse breakdown.
Voltage stays nearly constant despite large current changes
→ ideal voltage reference.
Used in voltage regulators, surge protection.
