diode current calculator
Calculate diode current from voltage using the Shockley equation or piecewise practical model. Enter Vd, Is, n, and T to get forward or reverse current (A).
reverse saturation current calculator
Calculates the current in a diode given the voltage using the precise Shockley equation and provides a convenient piecewise useful model of reverse leakage and high-current series-resistance characteristics.
Formula & Table Summary:
Id = Is * (exp( Vd / (n * Vt) ) - 1) Vt = k * T / q (≈25.85 mV at 300 K)
Inputs: Vd (V), Is (A), n (1–2), T (K). Output: Id (A).
diode current calculator
Input the diode voltage ( V d ), saturation current ( Is ), ideality factor ( n ) and temperature ( T ) to calculate diode current based on the Shockley equation. When used as a junction diode, also includes the effects of reverse leakage and series-resistance effects as parametric variations.This Diode Current Calculator solves a diode junction voltage (Vd) to diode current (Id) using the Shockley diode equation and approximate practical piecewise versions. Circuit analysis, bias calculation and fast leakage/or forward conduction estimates can be done with this tool. Warning: exponentials which are extremely large can be numerically unstable; usually bound by voltage range or logarithmic processing in use. When it comes to power dissipation, the product of returned Id and Vd is the diode dissipation (W).
