The very small current flows through the diode when the diode is in the reverse-biased state is called the reverse current of the diode. The reverse saturation current of a Germanium diode is of the orders ofmicro-amperes. While the reverse saturation current of a silicon diode is of the o...

Dark current, on the other hand, is the reverse saturation current of the pn junction when the photodiode is placed in dark. The value of dark current depends on the semiconductor material, operation temperature, and the area of the pn junction. A reduced junction area could result in ...
As a result, there is a tiny current flowing through the diode from positive to the negative side. The amplitude of this current is very small as the number of minority charge carriers in the diode is very small. This current is called reverse saturation current. ...
During this reverse recovery time of the diode, one can see that there will be fairly large amount ofcurrentflowing through the diode, but in the opposite direction (Irrin Figure 1). However its magnitude reduces and gets saturated to a value of reverse saturation current, once the time-line...
An inappropriate value for the emission coefficient can give incorrect temperature dependence, because saturation current is a function of the ratio of EG to N. If defining a finite reverse breakdown voltage (BV), then the value of the reverse BV is modulated by the reverse breakdown temperature...
Reverse saturation current depends on temperature. If temperature of junction increases , the minority charge carriers also increases. •The Width of Depletion Layer Practically The value of Depletion width vary from 0.1µm to 0.5µm
Photodiodes operated in photoconductive mode has high noise current. This is due to the reverse saturation current flowing through the photodiode. Dark current Dark current is the leakage current that flows in the photodiode in the absence of light. The dark current in the photodiode increase...
Reverse current IR: The current at a particular reverse voltage. This current is usually in the range of μA and hardly taken into account in analysis of power electronic circuits. • Conduction resistance RON: The equivalent resistance presented by the diode when forward-biased and conducting ...
