FAQs

Q1 : What is the breakdown voltage of a Zener diode?
A: The breakdown voltage of a Zener diode is the voltage at which the diode begins to conduct current in the reverse direction. This voltage is known as the Zener voltage or breakdown voltage.

Q2: What is the difference between a Zener diode and a regular diode?
A: A regular diode is designed to conduct current in one direction and block current in the opposite direction. A Zener diode is also designed to conduct current in the reverse direction, but it is specifically designed to operate in the breakdown region of its voltage-current characteristic curve, making it useful as a voltage regulator or reference.
