Why doesn't the voltage vary beyond breakdown voltage in zener diode?
The breakdown voltage of a Zener diode is the voltage at which the diode begins to allow current to flow in the reverse direction.
The breakdown voltage determines the maximum voltage that can be applied to the Zener diode before it begins to conduct in the reverse direction. This is an important factor in regulating voltage in electronic circuits.
The breakdown voltage of a Zener diode is influenced by factors such as the doping concentration of the diode, the temperature, and the physical structure of the diode.
The breakdown voltage of a Zener diode is typically measured using a voltage source and a series resistor. The voltage is gradually increased until the diode begins to conduct in the reverse direction, and the voltage at this point is the breakdown voltage.
Yes, the breakdown voltage of a Zener diode can be changed by altering the doping concentration or physical structure of the diode. This can be done during the manufacturing process or by applying a bias voltage to the diode.
