Leakage current is the small, unintended current that flows through a transistor, diode, or isolation structure when the device is in its off state, due to carrier diffusion, defects, or quantum tunneling. It appears in device characterization reports, circuit simulation notes, and power-management documentation, where standby current, temperature dependence, and process-corner variation are analyzed side by side with active power.
Leakage current appears in device datasheets, simulation model documents, and low-power design reviews. It also occurs in test specifications that set standby current limits and in failure analysis reports for abnormal power draw. Translators need to distinguish electrical leakage current from leakage inductance or fluid leakage, and to preserve the distinction between off-state leakage and gate leakage.
A common error is translating leakage current as 'leakage' in a way that suggests a defect or safety hazard rather than a specified off-state current. In datasheets this can mislead readers into thinking the part is damaged. It is also mistaken for leakage inductance or leakage power, which confuses electrical parameters and can distort power-management documentation.
Terminology must stay consistent across datasheets, design kits and patent filings. A single inconsistent parameter can propagate into fabrication decisions or weaken a patent claim, and IP confidentiality applies to every document in the chain.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
