Reverse leakage current in a semiconductor device is the current from that semiconductor device when the device is reverse biased. Mon-Fri, 9am to 12pm and 1pm to 5pm U. Register one! When a semiconductor device is reverse biased it should not conduct any currenthowever, due to an increased barrier potential, the free electrons on the p side are dragged to the battery's positive terminal, while holes on the n side are dragged to the battery's negative terminal. Your Account Log In Register. This produces a current of minority charge carriers and hence its magnitude is extremely small. This graph from the diode's datasheet enlarges the curvy, forward-region part of the i-v curve. An important conduction limitation of PN junction diode is leakage current. In all reverse-biased diodes, occurrence of leakage current is normal to some extent. Suppose you have an electric iron.
This article explains what the leakage current of a diode is. It is the current that will leak through a diode when the diode is receiving reverse voltage.
Semiconductor Devices Leakage Current Tutorialspoint
An important conduction limitation of PN junction diode is leakage current. When a diode is reverse biased, the width of the depletion region increases. It is seen that in a reverse-biased diode, some current flows through the depletion region. (December ) (Learn how and when to remove this template message).
Reverse leakage current in a semiconductor device is the current from that semiconductor The term is particularly applicable to mostly semiconductor junctions, especially diodes and thyristors. Reverse leakage current is also known as "zero.

Previous Page Print Page. What is leakage power in VLSI? Generally, this condition is required to restrict the current carrier accumulation near the junction.
What are the reasons for battery leakage through terminal posts? Ideallydiodes will block any and all current flowing the reverse direction, or just act like a short-circuit if current flow is forward.
What is leakage current Quora
That is considered and called leakage current.

|Originally Answered: What is Leakage current?
You can help Wikipedia by expanding it. More current means more voltage, less voltage means less current. Next we'll explore what an amazing variety of diodes there are and what purpose each type serves. Leakage current can also be viewed as a current which flows in the device when the input power to it is in off condition.

The reason And current following through the diode in reverse bias is leakage current. Leakage current definition: A leakage current is an electric current in an unwanted conductive path under normal | Meaning, pronunciation, translations and. The most important diode characteristic is its current-voltage (i-v) relationship. This defines More current means more voltage, less voltage means less current.
