In breakdown region, a Zener diode behaves as a
Updated On: Jun 8, 2024
- constant current source
- constant voltage source
- constant resistance source
- constant power source
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
When the reverse voltage across a zener diode exceeds the breakdown voltage $V_{Z},$ the current increases very sharply. In this region, the curve is almost vertical. It means voltage across zener diode is constant at $ V_{Z},$ even though the current through it changes. Therefore, a zener diode behaves as a constant voltage source.

Concepts Used:
Semiconductors
Semiconductors are a crystalline solid materials, whose electrical conductivity lies between a conductor and an insulator. Semiconductors are mainly used in the manufacturing of electronic devices like capacitors, transistors, diodes, Integrated circuits, etc.
Properties of Semiconductor:
- Semiconductor acts like an insulator at Zero Kelvin. On increasing the temperature, it works as a conductor.
- Due to their exceptional electrical properties, semiconductors can be modified by doping to make semiconductor devices suitable for energy conversion, switches, and amplifiers.
- Lesser power losses.
Uses of Semiconductor:
- Semiconductors are widely used in manufacturing electronics devices like transistors, diodes, sensors, integrated circuits.
- Semiconductors are widely used in all electronic devices, like mobile phones, digital cameras, communication devices, trains, ATMs, etc.
