Undesired current flow across the surface of a semiconductor device due to contamination of that surface. This disturbs the operation of the device and causes a variety of failures.
Insulators can also have surface leakage current for similar reasons.
In low voltage and electronics Leakage Current is any current that flows when the ideal current
The current of the minority charges (collector region) is the source of the leakage current. At higher temperature, this leakage current increases due to increase in thermal energy.
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
There are several formulas to find out leakage current, but one is the general electric current equation. This electric current equation is I=Qt.
The maximum allowable leakage current for any electrical device is 0.5 mA. This is equivalent to 0.5% of the rated current. This is a safety requirement to ensure that any current leakage is minimal and will not cause any harm to the user or damage to the device.Maximum allowable leakage current: 0.5 mAEquivalent to 0.5% of the rated currentIt is important to adhere to the safety requirements to ensure the safety of users and the protection of the device.

The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
In low voltage and electronics Leakage Current is any current that flows when the ideal current is zero. In medium and high voltage applications it is the current that flows either through the body or over the surface of an insulator. Leakage current often arises when outdoor insulation is submitted to conductive fog (sea mist/spray, industrial smogs) or when a pollution layer containing soluble salts is formed on the insulator surface and then wetted, for example by dew or mist. These currents can reach several hundred mA and may lead to flashover of the insulation.
by measuring the insulation resistance then by usig the formula for finding leakage current leakage current =voltage applied /resistance measured by megger.

Flow of current in the collector circuit produces heat at the collector base junction. This increases the temperature. More minority carriers are generated in base collector region, since more bands are broken,the leakage current increases. In other word, leakage current increase when temperature increase.
The leakage current in underground transmission line are any two conductors separated by an insulating medium. It constitutes a condenser and a capacitor.
