Conventional diodes are not used for voltage regulation because they lack the ability to maintain a constant output voltage across a wide range of input voltages and load conditions. Their forward voltage drop varies with current and temperature, making them unsuitable for precise voltage regulation. Instead, voltage regulation typically requires devices like Zener diodes or voltage regulators, which are designed to provide stable output voltages regardless of fluctuations in input voltage or load.

What is the function of zener?
zener diode is a revers bias diode which used for voltage regulation.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
What is a conventional diode?
A conventional diode is a semiconductor device that allows current to flow in one direction while blocking it in the opposite direction. It is typically made from materials like silicon or germanium and has two terminals: the anode and the cathode. When the anode is at a higher voltage than the cathode, the diode conducts; when the voltage is reversed, it does not conduct. Diodes are commonly used in rectification, signal modulation, and protection circuits.
Which type of circuit is used in zener diode?
A Zener diode is typically used in a reverse-bias configuration within a voltage regulation circuit. This circuit ensures that the Zener diode maintains a constant output voltage, even when the input voltage or load conditions vary. It is often implemented in simple power supplies to provide stable reference voltages or to protect sensitive components from overvoltage conditions.
What is the smallest load resistor that can be used and still maintain regulation in zener diode regulator?
The smallest load resistor that can be used while maintaining regulation in a zener diode regulator is determined by the zener diode's minimum load current (I_Z(min)) and the zener voltage (V_Z). The load resistor (R_L) must be calculated using Ohm's law, where R_L = V_Z / I_L, ensuring that I_L is at least equal to I_Z(min) to keep the zener in the breakdown region. If the load current falls below this threshold, the zener diode will not regulate the output voltage effectively.

Can the barrier voltage of a diode act as a voltage source?
No, we don not consider the barrier voltage of a diode to be able to act as a voltage source. The barrier voltage arises during construction of the p-n junction, and it results from charge separation. Separating charges results in voltage, but this difference of potential cannot be tapped as a voltage source because it cannot supply current the way we understand conventional voltage sources are able do.
Why zener diode is used as voltage regulator?
A: At one time it was used for a regulator because in the reverse voltage breakdown it has the characteristic of keeping the voltage constant as voltage is increased. IT has being replaced by many three terminal regulator with much better regulation and temperature coefficient

What type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
What is shunt regulator?
A shunt regulator is a type of voltage regulation circuit that maintains a constant output voltage by diverting excess current away from the load. It typically consists of a zener diode and a resistor; the zener diode conducts when the input voltage exceeds its breakdown voltage, allowing it to shunt excess current. This configuration provides stable voltage regulation for low-power applications but is less efficient at higher currents compared to series voltage regulators. Shunt regulators are commonly used in applications where precise voltage control is required without significant power loss.
