Enter the emission coefficient, reverse saturation current, and temperature into the calculator to determine the saturation current. This calculator helps in understanding the behavior of diodes and transistors at different temperatures.
Saturation Current Formula
The following formula is used to calculate the saturation current.
I_s = I_0 * e^{(n * 11600 / T)}Variables:
- I_s is the saturation current (A)
- I_0 is the reverse saturation current (A)
- n is the emission coefficient (unitless)
- T is the temperature (K)
To calculate the saturation current, multiply the reverse saturation current by the exponential of the product of the emission coefficient and 11600 divided by the temperature.
What is Saturation Current?
Saturation current is the current that flows through a diode or transistor when it is in a state of thermal equilibrium and no external voltage is applied. It is a critical parameter in semiconductor devices as it influences their operating characteristics. The saturation current increases with temperature and is also dependent on the material properties of the device.
How to Calculate Saturation Current?
The following steps outline how to calculate the Saturation Current.
- First, determine the emission coefficient (n).
- Next, determine the reverse saturation current (I_0) in amperes.
- Next, determine the temperature (T) in Kelvin.
- Next, gather the formula from above = I_s = I_0 * e^(n * 11600 / T).
- Finally, calculate the Saturation Current (I_s) in amperes.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
