The reverse saturation current in a PN junction diode is mainly due to the minority carriers. In a PN junction diode, the minority carriers are the electrons in the P-type material and the holes in the N-type material.

Here's a step-by-step explanation:

1. When a PN junction is reverse biased, the N-type material is connected to the positive terminal of the battery and the P-type material is connected to the negative terminal. This increases the barrier potential and widens the depletion region.

2. Despite this, thermal energy causes a few electrons and holes to cross the junction. These are the minority carriers.

3. The minority carriers (electrons in P-type and holes in N-type) that have enough energy to overcome the barrier potential contribute to a small current known as the reverse saturation current.

4. This current is very small and almost constant for a particular diode at a given temperature. It increases with an increase in temperature as more minority carriers get enough energy to cross the junction.

5. Therefore, the reverse saturation current in a PN junction diode is mainly due to the thermally generated minority carriers.
