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 type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
How does a diode change from AC to DC?
it clips all the bottom voltage off the sine wave,to get steady dc voltage you will need to clean up the ripple to get good voltage regulation <><><> A diode does not change AC to DC, but it does allow alternating current to flow in only one direction. A diode (or often 2 or 4 diodes) with a filter can be used to rectify AC into DC.
Discussion of zener diode a voltage regulation?
A zener diode has a relatively flat voltage to current curve when reverse biased. Within limits, you can consider that the voltage across the zener diode is constant. You can use the zener as the primary regulator, so long as you consider the power requirements and dissipation of both the zener and the load, and you do not overload the zener. More often, the zener is used as a voltage reference in a larger power supply that uses other components, linear or switched, to supply the load.

Which electrical component regulates current and voltage?
People have used a ballast for current regulation and you can use a breakdown diode for voltage regulation.
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
Why zener diode is called reference diode?
They are frequently used to provide a voltage reference in voltage regulators.
Is it pn junction diode used as voltage regulator?
zener diode
What type of diode is a HVR-1X4 diode?
It's a high voltage diode, typically used in microwave ovens.
What is V-I characteristics of zener diode?
Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
Which is better 3 percent voltage regulation or 5 percent voltage regulation?
Percent Regulation is the regulation expressed as a percentage is a figure of merit used to specify the performance of a voltage regulator.
Can zener diode used as rectifier?
Yes **************************************** Yes they can but there are pitfalls. A normal diode will have a high reverse breakdown voltage. A zener has a relatively low breakdown voltage (its "zener"voltage). If a zener diode is used as a rectifier it must have a zener voltage at least twice the peak of the applied a.c.
