What is zener break down voltage?
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.-- Dinakar
Did the armature voltage reverse its polarity?
yes
What is Meaning of diode rating?
There are two diode ratings. One is the forward current rating, and the other is the reverse breakdown voltage rating. The forward current rating is the maximum current that the diode can conduct before failing, and the reverse breakdown voltage rating is the maximum reverse voltage that can be applied before failing. Of course, the reverse voltage rating has a different meaning in a zener diode, but this answer applies to ordinary diodes.
What is the explanation for the Operation of varicap diode?
The capacitance of a varicap diode varies as the reverse voltage to the diode changes. As you increase the reverse voltage, the capacitance decreases. And vice versa.
Explain the output wave form a circuit which has a zener diode in reverse biased?
A zener diode has a relatively constant reverse voltage, at the designated zener voltage. If you had a circuit, say, with an AC source, a resistor, and a zener, the waveform across the zener would be the AC source, clipped at the reverse bias zener voltage, and clipped again at the forward bias voltage, typically about 0.7 V.
What do you mean by peak reverse voltage of semiconductor diode?
Peak reverse voltage of a diode is the maximum reverse bias voltage can be applied to diode which does not cause break down.
Define rms reverse voltage of a diode?
A DIODE will breakdown at a certain reverse voltage if RMS VOLTAGE IS SPECIFIED THEN the actual voltage will be RMS volts times 1.41
Is fwd break over voltage is greater than reverse breakdown voltage i.e VboVbr?
forward breakover voltage is slightly smaller than reverse breakdown voltage
Break down voltage?
The breakdown voltage of an insulator is the minimum voltage that makes it partially conductive electrically. On the other hand, the breakdown voltage in a diode refers to the minimum reverse voltage to cause it to conduct in reverse.
Which voltage is greater in thyristor whether forward breakover or reverse breakdown voltage?
One voltage is greater in thyristor whether forward breakover or reverse breakdown voltage. The greater of the two voltages in thyristor is forward breakover voltage.
Difference between diode and zener diode?
All diodes have a tiny voltage when current flows in a 'forward' direction. And a Reverse Breakdown voltage when current tries to flow in a reverse direction resulting in a high voltage. That current does not flow until voltage exceeds its breakdown number. Regular diodes have a reverse breakdown voltage that is somewhere above a number, For example a 1N4002 has a Reverse Breakdown Voltage somewhere above 100 volts. A Zener diode is constructed so that its Reverse Breakdown voltage is clearly defined and accurate. For example Reverse Breakdown voltage for a 1N4733 is 5.1 volts. A !N4734 is 5.6 volts.
What resistance does a practical diode offer under reverse-biased conditions if the applied reverse voltage is greater than the breakdown voltage?
A normal diode with reverse voltage in excess of its rated breakdown voltage could fail. Resistance could be high (blown open) or low (shorted).

What resistance does a practical diode offer under reverse-biased conditions if the applied reverse voltage is less than the breakdown voltage?
A practical diode under reverse-biased conditions, if the applied reverse voltage is less than the breakdown voltage, will offer a high resistance, usually in excess of 10 megohms. In a practical circuit, the diode would appear to be open.
Did the armature voltage reverse its polarity?
yes
Which voltage is greater in thyristor whether forward break over or reverse breakdown voltage?
It is stated that one of the voltage is greater in thyristor whether it be forward breakover or reverse breakdown voltage. It is also stated that the greater of the 2 voltages in thyristor is the forward breakover voltage.
What means 1N4007 diode?
A: 1N400X signify a power rectifier series the last the X define the reverse voltage breakdown sustainable capability A 1N4001 is for example a 50V reverse voltage breakdown A 1N4007 is a 1000V reverse voltage breakdown
