A rectifier diode normally allows current to pass in one direction (the forward direction), and almost no current in the opposite direction (the "reverse" direction). The diode is designed to work up to a certain voltage; if more than a certain voltage is applied in the reverse direction, it will "break down", and suddenly a large current will flow. This can irreparably damage the rectifier diode, unless it is of a type specifically designed to operate in the breakdown region - i.e., a Zener diode.

What is the cut in voltage of germanium and silicon diodes?
cut in voltage *** for silicon is 0.7volts and that for germanium is 0.3volts.According to Millman and Taub, "Pulse, Digital and Switching Waveforms", McGraw-Hill 1965, the cutin (or offset, break-point or threshold) voltage for a silicon diode is 0.6, and 0.2 for germanium.Breakdown voltage is another thing entirely. It is the reverse voltage at which the junction will break down.
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 will happen if the supply voltage polarity is reveresed for the case of using a diode with piv of 4.8 volt?
If we give more than 4.8 volt to a diode in reverse bias condition it will break down or destroyed.
What are the release dates for Break It Down - 2015?
Break It Down - 2015 was released on: USA: 1 January 2015
What is the name of the transformer that reduces the voltage?
a step down transformer is used to lower the voltage from the powerlines into your home. a common slang term for this type of transformer is a pole pig.
What is the break down voltage point for a zenerdiode?
The breakdown voltage point for a Zener diode is 17 volts
Break down occurs in diode because of?
reverse voltage applied
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.
Does the material of the diode depends on break down voltage?
A Germanium diode has a much lower breakdown voltage than a silicone diode.
A zener diode operates in?
In a reverse bias higher than the break down voltage.
Why doesn't zener diode have negative resistance?
because of its high break down voltage.
What is the difference between cut in and break down voltage?
what is the difference between cut- in and cut -out
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.
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.
When excessive voltage is applied to a capacitor it will break down What factor of the capacitor has the greatest effect on breakdown voltage?
The dielectric material between the plates.
What is break down?
it is the minimum revers voltage at which P N Junction brake down with sudden rides in reverse current.
Which is greater the breakdown voltage or the barrier potential?
Breakdown voltage is far greater than barrier potential. silicon:- break-down voltage :- 5v - 450 v barrier potential ;- 0.5v to 0.7 V
