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.

What is the source of leakage current in a transistor?
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.
What is the definition of reverse leakage current?
Reverse leakage currentin asemiconductordevice is thecurrentfrom that semiconductor device when the device isreverse biased.When asemiconductordevice isreverse biasedit should not conduct anycurrentat all, even though, as a temperature effect, it will form electron-hole pairs (seeCarrier generation and recombination) at both sides of the union and therefore a very small current, which is namedReverse leakage current, and this current doubles for each increment of 10°C in temperature. The current is caused by electron hole pairs being swept across the electric field of the depletion region when generated thermally near the edge.
What is leakage current in transformer?
In low voltage and electronics Leakage Current is any current that flows when the ideal current
What are the factors affecting the stability of a Q-point?
(1) current amplification factor due to change in temperature. (2) collector current because of variation in leakage current.
What are the factors affecting stability of q point?
(1) current amplification factor due to change in temperature. (2) collector current because of variation in leakage current.
Which current is the leakage current that flows through a photo diode with no input in a light detector?
leakage current itself
What is the leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What is leakage current of zener diode?
The leakage current of a (zener) diode is the current that leaks when a diode is connected in reverse biased.
What is the effect of temperature in the diode reverse characteristics?
The reverse characteristics of a diode are significantly influenced by temperature. As temperature increases, the reverse saturation current also increases due to the enhanced thermal generation of charge carriers, leading to a higher leakage current. This can result in a lower breakdown voltage and a shift in the reverse voltage characteristics. Additionally, the temperature dependency can affect the diode's overall reliability and performance in circuit applications.
Is barrier potential temperature dependent?
Yes, the barrier potential in a semiconductor diode is temperature dependent. As temperature increases, the barrier potential decreases due to changes in the band gap energy and carrier density, leading to increased leakage current. Conversely, as temperature decreases, the barrier potential increases, reducing the leakage current.
How do you test leakage on equipment?
by measuring the insulation resistance then by usig the formula for finding leakage current leakage current =voltage applied /resistance measured by megger.
What is the formula of getting leakage current?
There are several formulas to find out leakage current, but one is the general electric current equation. This electric current equation is I=Qt.
