Formula Used in “Shockley Diode Calculator”
The Shockley Diode Calculator employs the following standard formula to determine the current flowing through a Shockley diode:
I = I0 * (e(V/VT) – 1) – V/(R)
Where:
- I = Current through the diode (Amperes)
- I0 = Reverse saturation current (Amperes)
- V = Voltage across the diode (Volts)
- VT = Thermal voltage (Approximately 26mV at room temperature)
- R = Resistance in series with the diode (Ohms)
Step-by-Step Breakdown of the Formula
To effectively utilize the Shockley Diode Calculator, follow this step-by-step breakdown of the formula:
- Determine the Reverse Saturation Current (I0): This value is generally found in the diode’s datasheet and represents the current that flows when the voltage is reverse biased.
- Measure the Voltage (V) Across the Diode: Use a multimeter to measure the voltage across the diode under the working condition.
- Calculate the Thermal Voltage (VT): At room temperature (~300K), this is approximately 26mV. You can use the formula VT = (kT)/q, where k is the Boltzmann constant, T is the absolute temperature in Kelvin.
- Identify the Series Resistance (R): Measure or find the value of any resistance that is in series with the diode, which can affect the current.
- Plug Values into the Formula: Substitute the identified and measured values into the Shockley diode equation to find the current flowing through the diode.
Example Calculation
Let’s consider an example using the Shockley Diode Calculator:
| Parameter | Value |
|---|---|
| Reverse Saturation Current (I0) | 1μA (1 * 10-6 A) |
| Voltage Across Diode (V) | 0.7V |
| Thermal Voltage (VT) | 26mV (0.026V) |
| Series Resistance (R) | 10Ω |
By plugging the values into the formula, we can find the current:
I = (1 * 10-6) * (e(0.7/0.026) – 1) – (0.7/10)
This simplifies to:
I ≈ (1 * 10-6) * (e(26.92) – 1) – 0.07
Calculating further:
I ≈ (1 * 10-6) * (4.593 x 1011 – 1) – 0.07
I ≈ (1 * 10-6) * (4.593 x 1011) – 0.07
I ≈ 459.3 mA – 0.07 A
I ≈ 459.23 mA
Thus, the current flowing through the diode is approximately **459.23 mA**.
