What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What type of diode is used to convert alternating current into direct current?
The type of diode used to convert alternating current in to direct current is the power diode.
What is the main function of diode?
the main function of the diode is to allow current to flow in just one direction and oppose the flow of current in negative direction.In short diode rectifies the current..
What is Reverse Saturation Current of a diode?
When a diode is operated as reverse bias the current flow is almost completely blocked. A small amount of current is still able to travel in reverse through the diode and this is referred to as the reverse current saturation.
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 does a protection diode do?
It will conduct electricity when the voltage across its terminals reaches a certain value. Once the over voltage is extinguished, the protection diode becomes an open circuit again. Therefore, you need to connect a protection diode between both wires to be protected (differential mode) and from each wire to ground (common mode). Protection diodes are primary protection devices (fast reacting), but they cannot handle too much current. That is why they need to be used with secondary protection devices (fuses and gas arrestors) to provide better protection.
What is breakdown diode?
a break down diode is a diode that allows current to flow freely in one direction but not in the other the difference between it and a standard diode is that it is a semiconductor in the direction that current doesn't flow freely in current only flows in this side when the voltage reaches a set point and the resistance then breaks-down and allows the current to flow it is useful where the circuit might require low voltage protection
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What is diode reverse current?
the current which has negative value n passes through the diode is called as diode reverse current
What is leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
How does a constant current power supply works?
these are essential for circuits which are current sensitive, it regulates the amount of current which serves as protection for circuits. it is commonly used in Laser diode applications.
What type of current is used in zener diode?
A zener diode passes drect current, and the point of a zener diode is that the voltage across it stays nearly constant over a range of different currents, so it can provide a supply of stabilised voltage.
What the three types of over current protection relay and describe the principles of operation?
over current protection relay
What is breakdown in diodes?
a break down diode is a diode that allows current to flow freely in one direction but not in the other the difference between it and a standard diode is that it is a semiconductor in the direction that current doesn't flow freely in current only flows in this side when the voltage reaches a set point and the resistance then breaks-down and allows the current to flow it is useful where the circuit might require low voltage protection
When does the diode not allowed to flow the current?
A diode is a one-way gate for electrical current to flow through. You must have the right size diode for the amount of current that will be used in your circuit. The stripe on the diode is your output end. That is, the current must enter your diode at the non-stripe end and leave at the end with the stripe. This coincides with the diode symbol used on your schematic. If your diode is in backwards, the circuit will not work as the gate in the diode will block the current just the way it should.
What type of diode is used to convert alternating current into direct current?
The type of diode used to convert alternating current in to direct current is the power diode.
What is unit of diode?
The unit of a diode is the ampere (A), which measures the flow of electric current through the diode. It indicates the amount of current passing through the diode at a given moment.
