Is leakage current same as reverse current?
Reverse saturation current terminology is generally used in diode whereas leakage current is used in BJT. But both are more or less indicates the same quantity, i.e leakage current and reverse saturation current is flowing due to the minority carriers.
What causes reverse leakage current?
Reverse-Bias pn Junction Leakage Current This results in reverse-biased leakage current in the device. This leakage current can be due to drift/diffusion of minority carriers in the reverse-biased region and electron-hole pair generation due to the avalanche effect.
What causes a small leakage current in a reverse biased pn junction?
Minority carriers of each material are pushed through the depletion zone to the junction. This action causes a very small leakage current to occur. Generally, leakage current is so small that it can be considered as negligible.
What causes reverse current in diode?
If a large enough negative voltage is applied to the diode, it will give in and allow current to flow in the reverse direction. This large negative voltage is called the breakdown voltage.
What is reverse leakage current in diode?
Reverse leakage current in a semiconductor device is the current from that semiconductor device when the device is reverse biased.
What is reverse current in PN junction?
Reverse Current in PN Junction When a p-n junction is connected across a battery in such a manner that its n-type region is connected to the positive potency of the battery and the p-type region is connected to the negative potency of the battery the p n junction is said to be in reverse biased condition.
What is diode reverse leakage current?
What is leakage current in a PN junction diode?
The leakage current of diode is the current that the diode will leak when a reverse voltage is applied to it.
What is reverse current in pn junction?
What is reverse breakdown current?
What It Is: Reverse breakdown voltage is the reverse anode voltage at which the diode conducts a specified amount of reverse current. Since it’s the reverse current across a junction, IR exhibits a knee shaped rise, increasing rapidly once breakdown occurs.
What is reverse breakdown?
Glossary Term: Reverse-Breakdown-Voltage Peak Inverse Voltage (PIV) or Peak Reverse Voltage (PRV) refer to the maximum voltage a diode or other device can withstand in the reverse-biased direction before breakdown. Also may be called Reverse Breakdown Voltage.
What is reverse bias in PN junction diode?
Reverse Bias When the p-type is connected to the negative terminal of the battery and the n-type is connected to the positive side then the p-n junction is said to be reverse biased. In this case, the built-in electric field and the applied electric field are in the same direction.
What is a reverse biased p-n junction diode?
The process by which, a p-n junction diode blocks the electric current in the presence of applied voltage is called reverse biased p-n junction diode.
What is the leakage current in a reverse biased diode?
To get a more general idea, In a reverse biased diode, a current still flows inside the diode known as the reverse saturation current or the leakage current.
What causes pn junction leakage current?
A. pn Junction Reverse-Bias Current Drain and source to well junctions are typically reverse biased, causing pn junction leakage current.
What are the conduction limitations of PN junction diode?
An important conduction limitation of PN junction diode is leakage current. When a diode is reverse biased, the width of the depletion region increases.
