Pickout the incorrect statement regarding reverse saturation current in the `p-n` junction diode.

Options

A. Reverse saturation current is also known as leakage current
B. Current doubles of every `100^(@) C` rise in temperature
C. Current carriers are produced by thermal agitation
D. Current is due to minority carriers

Answer

To determine the incorrect statement regarding reverse saturation current in a p-n junction diode, we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Understanding Reverse Saturation Current**:
- Reverse saturation current, also known as leakage current, occurs when a p-n junction diode is reverse-biased. In this condition, the diode does not conduct significant current, but a small amount of current flows due to minority carriers.

2. **Analyzing the Statements**:
- **Statement 1**: "Reverse saturation current is also known as leakage current."
- This statement is **correct**. The reverse saturation current is indeed referred to as leakage current because it represents a small amount of current that leaks through the diode when it is reverse-biased.

- **Statement 2**: "Current doubles for every 100 degree Celsius rise in temperature."
- This statement is **incorrect**. While it is true that reverse saturation current increases with temperature, it does not necessarily double for every 100 degrees Celsius. The relationship is more complex and depends on the specific material properties of the diode.

- **Statement 3**: "Current carriers are produced by thermal agitations."
- This statement is **correct**. In a reverse-biased diode, minority carriers are generated due to thermal energy, which causes some electrons and holes to be produced.

- **Statement 4**: "The current is due to minority carriers."
- This statement is **correct**. The reverse saturation current is primarily due to the movement of minority carriers in the p-n junction.

3. **Conclusion**:
- After analyzing all the statements, we find that **Statement 2** is the incorrect statement regarding reverse saturation current in a p-n junction diode.

### Final Answer:
The incorrect statement regarding reverse saturation current in the p-n junction diode is: "Current doubles for every 100 degree Celsius rise in temperature."
