its simple.reverse saturation current is because of the flow of minority carriers across the junction when the bias is changed suddenly from forward to reverse.this is why it doesnt depend on forward bias

What is meant by reverse saturation current?
reverse saturation current is produced by the thermal activity of the diode materials. This current: 1- Is temprature dependant; that is, it increases as temprature. 2- Accounts fot the major portion of diode reverse current surface leakage current is produced by contamination on the surface of the device, allowing current flow to bypass the junction
What is reverse saturation current in ideal diode?
When a pn junction is reversed bias practically no current flows through it ,but a very small current flows through due to minority charge carriers ,which is known as reverse saturation current .In p type due to electrons and in n type due to holes .
What is saturation in current in diod?

What is saturation in current transformer?
When the curent Is in the secundary for the highervalues Ip in the primary coil are not equal proportional than for the lower curent. Is/Ip for lower values is for exemple 100 Is/Ip for higher values are for exemple 70The reason is the magnetique flux saturation in the closed iron core.Roger
When both junctions of npn diode are reverse biased?
When p-n junction of a diode reversed biased then majority carriers are not able to cross the junction and are attracted in respective regions.So current becomes approximately zero.But because of minority carriers a reverse current keeps flowing.It is called Reverse Saturation Current.And due to attraction towards sides,charges go away from junction.So width of depletion reason increases.
Reverse saturation current of Ge diode?
Reverse saturation current of germanium diodeThe current that exists under reverse bias conditions is called the reverse saturation current. Reverse saturation current of the germanium diode is typically 1 micro ampere or 10-6 a.At a fixed temperature, the reverse saturation current of a diode increases with increase in applied reverse bias. In reverse bias region the reverse saturation current also varies with the temperature.
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.

What is Icbo in transistors?
Icbo (collector to base current when emitter is open) also called reverse saturation current as Is in reverse bias p-n junction diode.Regards
Define reverse saturation current?
In diode some current flows for the presence of the minority charge carriers. This current is known as reverse saturated current. This is generally measured by picoampere. This current is independent of reverse voltage. It only depends on the thermal excitation of the minority carriers
How is reverse current in a diode produced?
The main reason for produce reverse current in a diode is "MINORITY CARRIERS". For reverse bias diode i.e negative terminal connected to p side and positive to n side the electrons in p side(minority charge carriers) attracted towards the positive polarity i.e towards positive terminal. Hence the current (reverse saturation) flows.Holes also contributed the current by attracting towards negative side.

Why multimeter not measuring a peak value?
Reverse saturation current of silicon is in nano ampear therefore it is prefered over germanium
What is saturation region in general?
Saturation region is one in which the output current is independent of the input and remains almost constant. Hence, MOSFETs in saturation are modeled as current sources( whose current is independent of voltage across it)
