The point in the forward operating region of the characteristic curve where conduction starts to increase rapidly is called Knee voltage of a PN Junction Diode.
The breakdown voltage of a diode is the minimum reverse voltage to make the diode conduct in reverse.(or) Breakdown voltage is a parameter of a diode that defines the largest reverse voltage that can be applied without causing an exponential increase in the current in the diode.

What is the break down voltage point for a zenerdiode?
The breakdown voltage point for a Zener diode is 17 volts
Why doesn't zener diode have negative resistance?
because of its high break down voltage.
What is break down region of zener diode?
Zener breakdown is the phenomena wherein the Zener diode experiences reverse breakdown at a much lower voltage than a normal diode, which may breakdown in excess of 100 volts, depending on the type. This is useful because the Zener will hold the same voltage after breakdown, regardless of the input voltage, making them excellent for voltage controlled switches and references.
What happens to the current when the voltage becomes limited at the knee?
A: Perfect example is a zener. As input voltage increases the current at the knee increases almost linearly at the zener voltage. If the inputs varies up or down then the current will vary up or down at the preset voltage making a zener a voltage regulator because of this feature
What is a zener diod?
A Zener diode is a type of diode that sends current in the forward way like a normal diode, but also in the reverse direction if there is voltage that is larger than the breakdown voltage which is also known as "Zener voltage". The apparatus was named after Clarence Zener, who discovered this electrical property.
Explian action of zener diode as a regulator?
Zener predicatively will break down at a voltage as manufactured and sustain that voltage as long as the source can provide the current. The limitation is the zener power dissipation for each device. It Regulates by maintaining that breakdown voltage until its current is reduced or its break down voltage is reduced.

In a reverse bias higher than the break down voltage.
Why doesn't zener diode have negative resistance?

When a 3.3V zener diode and a 5V zener diode are connected in parallel what is the average reverse break down voltage?
There will be no "average" reverse breakdown voltage. When the applied voltage reaches 3.3v, the 3.3v zener will conduct and the voltage will go no higher. The 5v zener will never conduct because the voltage across it will never go higher than 3.3v The only way the 5 volt zener will ever conduct is if the 3.3v zener fails. ALAN H.

When a 3.3 V zener diode is parallel with a 7 V zener diode what is the break down voltage?
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
What happens to the current when the voltage becomes limited at the knee?

Why an ordinary diode suffers avalanche break down rather than zener break down?
An ordinary diode is designed to have a high breakdown voltage, causing it to experience avalanche breakdown when the reverse bias voltage surpasses its breakdown voltage. In contrast, a Zener diode is engineered with a specific doping profile that allows it to exhibit Zener breakdown at lower voltages by enabling electron tunneling across the depletion region. This fundamental difference in design leads to the distinct breakdown behaviors in each type of diode.
What is a zener diod?
A Zener diode is a type of diode that sends current in the forward way like a normal diode, but also in the reverse direction if there is voltage that is larger than the breakdown voltage which is also known as "Zener voltage". The apparatus was named after Clarence Zener, who discovered this electrical property.
How is the zener diode connected to protect the load?
A: A zener is a diode that if reversed voltage is applied will conduct at a certain voltage. This diode zener therefore will conduct at a preset voltage limiting the over voltage to the diode conducting voltage and no more so the load can see the voltage up to the zener voltage and no more because the zener will sink the extra current from over voltage situation.
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.
