Reverse saturation current is the collector current when emitter is open circuited and base-collector junction is reverse bias mode. In this mode of operation collector-base junction act as a reverse biased diode. The current in this reverse biased junction is known as reverse saturation current.

Reverse Saturation Current of Common Emitter Transistor
Definition
Reverse saturation current (Ico) of a common emitter transistor is the collector current when the emitter is open-circuited and the base-collector junction is reverse biased.
Explanation
When the emitter is open-circuited and the base-collector junction is reverse biased, the collector current that flows is due to the minority carriers in the base region. These carriers are injected into the collector region by the reverse-biased base-collector junction, and they contribute to the collector current.
The magnitude of the reverse saturation current depends on the doping levels and dimensions of the transistor. It is typically a small value, on the order of nanoamperes.
Importance
The reverse saturation current is an important parameter in the analysis and design of transistor circuits. It affects the biasing, gain, and dynamic performance of the transistor. In particular, it sets the lower limit on the collector current that can be achieved in a given circuit, and it determines the noise performance of the transistor.
Conclusion
In summary, the reverse saturation current of a common emitter transistor is the collector current when the emitter is open-circuited and the base-collector junction is reverse biased. It is an important parameter in the analysis and design of transistor circuits.
