Junction Leakage Calculator
Scale a reverse-biased junction's saturation current density by its area to total leakage current.
Description
Scale a reverse-biased junction's saturation current density by its area to total leakage current.
Junction Leakage Calculator is a focused tool for the following task. Scale a reverse-biased junction's saturation current density by its area to total leakage current. It reports Leakage current from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.
When to use Junction Leakage
Use this semiconductor calculation for first-order device, material, fabrication, interconnect, packaging, or reliability estimates when every coefficient and unit convention is known.
- Junction area (um^2)
- Required number in um^2. Area of the reverse-biased junction.
- Saturation current density (pA/um^2)
- Required number in pA/um^2. Saturation leakage current density.
The cited overview of P–n junction supplies background for the terminology and domain context used by this tool.1
How Junction Leakage works
Scale a reverse-biased junction's saturation current density by its area to total leakage current. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Leakage current (pA)
- Returned number in pA. Total junction leakage current.
Limitations and assumptions
- Material composition, geometry, process history, temperature, electric field, bias, interfaces, parasitics, and fitted parameter ranges can invalidate a compact semiconductor model.
- Junction area must be at least 5e-324.
- Saturation current density must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
Compare the estimate with measured process data, current device documentation, and a higher-fidelity circuit, field, thermal, quantum, or TCAD model when the decision requires it.

Extract the positive Shockley saturation-current parameter from one forward-bias point using Is = I/[exp(V/(n·Vt))−1]. The logarithmic evaluation remains stable at high forward voltage. This parameter is not necessarily equal to a diode's measured reverse-leakage current.
