a close approximation of the forward current is an exponential function of voltage, but it has constants that must be empirically adjusted for accuracy. the reverse breakdown is a bit tricker to model accurately.
The function look something like this: I = K1 eK2(V-K3)

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 maintains constant current?
zener diode
How much current draw zener diode?
It depends on the particular zener diode. Typically, they will pull 75 ma of current.
What is Transit time in transistor or diode?
A transistor is a switch. A diode directs the flow of current.
Why diode don't allow the current coming in opposite direction?
Diode is known as a rectifier because it only allows the current to flow in one direction. Diode is only effective when the input is AC.
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.

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 type of diode maintains constant current?
zener diode

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.
List the two conditions under which a diode is operated?
A diode is a semiconductor material which has p region and n region. In order to "turn on" and conduct current in the forward direction, a diode requires a certain amount of positive voltage to be applied across it. An ideal diode conducts only when the diode is forward biased, and then the voltage drop across the diode (Vd) is zero. When the ideal diode is reverse biased, no current flows. The two conditions to operate a diode are: (a) Current flow is permitted; the diode is forward biased. (b) Current flow is prohibited; the diode is reversed biased. When the polarity of the battery is such that current is allowed to flow through the diode, the diode is said to be forward-biased.
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 the highest forward current in the diode 1N4007 and 1N5002?
maximum forward current in diode IN4007 is 30 amp
