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.
What is the primary difference between a zener diode and PN-junction Diode?
ZENER DIODE IS MADE TO REVERSE BREAK OVER AT A CERTAIN VOLTAGE the break over knee is not exactly sharp especially in low voltage zeners. and p-n means positive and negative junction
When a diode is properly forward biased what is the voltage drop across it equal to?
The forward biased voltage drop of a diode depends on the type of diode and the current through the diode. A typical silicon diode will exhibit a voltage drop between 0.6v and 1.4v depending on current. An LED might range from 2v to 3v. A germanium diode might go a low as 0.2v. Bottom line; it varies.
What are the amount of voltage across the diode?
The amount of (forward biased) voltage across a diode is dependent on current and temperature. A typical silicon diode has a forward voltage of about 0.6V at low current and temperature. As current goes up, voltage goes up slightly, with a typical voltage being 1.4V at high current. As temperature goes up, voltage goes down slightly, but the maximum current rating also goes down.
What is the difference between rectifier diode and zener diode?
A: They are both diodes. The difference lies in the application. A rectifier is used to rectify AC current into pulsating current. The zener diode is used to regulate a voltage source to the zener voltage when connected in the reverse direction. ************************************************************** If you look at the characteristic curves of a rectifier diode and a zener diode, you will see that they are similar, but the reverse curve of the zener has a much sharper bend at what is called the "knee". It is at this point on the zener's curve at which it operates.
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.
PN junction diode made of silicon is the value of voltage depends exponentially on the current through the diode.?
current depends exponentially on voltage: diode equation (approx.) Idiode=k (exp (Vdiode/Vth)-1) k=constant (saturation current, something like a femto ampère) Vth=KT/q => 25.8 mV @ T=300 K, Vth is thermal voltage K=Boltzmann's constant T=junction temperature (Kelvin) q=electron charge
Break down occurs in diode because of?
reverse voltage applied
What is the break down voltage point for a zenerdiode?
The breakdown voltage point for a Zener diode is 17 volts
What is the value of the breakdown voltage for zener diode?
It depends on the particular diode. They come in all different values.
What is the input voltage at which a diode will pass current?
As close to virtually zero volts as is possible: the current will very small but there will be current. This depends on two things: the material that is used to make the diode, and whether the voltage is applied in a forward or reverse direction to the diode. A typical silicon diode will pass forward current above 0.6 V and pass no reverse current until a much higher voltage is applied (check the rated peak inverse voltage PIV)
What is the primary difference between a zener diode and PN-junction Diode?
ZENER DIODE IS MADE TO REVERSE BREAK OVER AT A CERTAIN VOLTAGE the break over knee is not exactly sharp especially in low voltage zeners. and p-n means positive and negative junction
Can a lower voltage zener diode be used?
It depends on the design of the circuit.
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
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.
How do you forward-bias a diode?
You need to apply an external voltage across the diode. The negative terminal must be connected to the N type material.
