What else can I help you with?
What is the minimum required peak voltage rating for a diode with voltage source is 100V peak?
200 V
What is dropper diode voltage regulator?
The dropper diode voltage regulator is a type of voltage regulator. It is comprised of a single diode that serves as the voltage regulating device.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
What will a Zener diode do at breakdown voltage?
A Zener Diode will continue to show its breakdown characteristics until it gets fried...for example a 5 volt zener will get fried at a breakdown voltage of about 6 volts..this happens because of the large amount of current flowing through the small diode which unfortunately the diode cannot handle.
What is the cutting voltage of a silicon diode?
It is not 'Cutting voltage' but it is Cut-in voltage'. It is the voltage at which the diode turns ON. For silicon it is 0.7v. After reaching 0.7V diode current starts increasing rapidly for little increase in voltage.
Which diode has its characteristics very close to that of an ideal voltagesource.1.zener diode 2.vacuum tube diode 3. crystal diode?
The Zener diode has the characteristics of a constant voltage source.
What is V-I characteristics of zener diode?
Work in reverse bias.(breakdown at a particular voltage to keep the volt. constant so used as voltage regulator) same as diode when forward biased.
What will happen when a dc source is used in front of a diode in half wave rectifier?
If the DC source biases the diode off, then the output will be zero. If it biases the diode on, then the output will be DC, with the voltage being nearly the same as the input voltage.
Can the barrier voltage of a diode act as a voltage source?
No, we don not consider the barrier voltage of a diode to be able to act as a voltage source. The barrier voltage arises during construction of the p-n junction, and it results from charge separation. Separating charges results in voltage, but this difference of potential cannot be tapped as a voltage source because it cannot supply current the way we understand conventional voltage sources are able do.
What are the limiting values of a PN junction Diode?
A: heat And PIV(Peak Inverse Voltage) or so called Peak Reverse Voltage is limit the diode characteristics.
Why can't the potential barrier of a diode be used as a voltage source?
The potential barrier of a diode is caused by the movement of electrons to create holes. The electrons and holes create a potential barrier, but as this voltage will not supply current, it cannot be used as a voltage source.
What is the minimum required peak voltage rating for a diode with voltage source is 100V peak?
200 V
If diode is connected to two voltage sourceone in forward biased other biased diode in rewrse what will be net effect of two source on diode?
If a diode is connected with two voltage sources for ex: One is 5V in F.B and The other is 3V in R.B then the Effective voltage will be equal to 2V F.B. So, The diode conducts.
Voltage-current characteristics of ideal diode?
An ideal diode would match the purpose of a diode without any of the drawbacks. The purpose of a diode is to control current flow - The diode "turns on" for current flowing in one direction, and "turns off" if current wants to flow in the other direction. Ideally, there would be no voltage drop across this diode when allowing current flow, thus no power loss. When the diode is "turned off" by a negative voltage, idealy there would be no current flow (no matter how large the negative voltage).
What is dropper diode voltage regulator?
The dropper diode voltage regulator is a type of voltage regulator. It is comprised of a single diode that serves as the voltage regulating device.
How will you differentiate the diodes whether it is Zener or avalanche when you are given two diodes of rating 6.2 v and 24V?
Oh, what a happy little question! To differentiate between Zener and avalanche diodes, you can look at their voltage ratings. A Zener diode typically has a lower voltage rating, like 6.2V, while an avalanche diode usually has a higher voltage rating, like 24V. Just remember, each diode has its own special purpose and they all bring joy to our electronic landscapes.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).
