What is Zener resistance of the Zener diode?

zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode


When current through a zener diode increases by a factor of 2 by what factor does the voltage across the zener diode increase?

If the zener diode is in zener breakdown the voltage across the zener diode remains constant regardless of current (for the ideal zener diode). Real zener diodes have parasitic resistance that causes the voltage across the zener diode to increase slightly with increased current, but due to temperature dependant variations in this parasitic resistance as well as temperature dependant variations in the zener breakdown voltage, this change in voltage in real zener diodes cannot be described by a simple linear factor.


Does a zener diode acts as a switch?

A zener diode cannot be used as switch.


Why the zener current taken five times the load current in zener diode as voltage regulator?

A: There is no X times current for a zener to regulate. The real limit is the zener power dissipation that determine the total current since the zener to regulate must carry its own breakdown current in addition to the load current when the load is absent . IF this is not taken in consideration the zener will surely burn out


What is the forward voltage of a silicon based zener diode?

It would be 0.7V, the same as any other silicon diode; except for one thing, most zener diodes are manufactured with a reversed diode in series with them. When the zener is operated in its normal zener breakdown mode this reversed diode conducts, letting the zener operate. When the zener is operated in its forward biased mode this reversed diode prevents conduction. Thus most zeners have no forward voltage.

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.
