The value of leakage current is mainly dependent on
Options:
a. Temperature
b. Degree of doping
c. Physical size of junction
d. All of the above
Correct Answer: d. All of the above
Explanation:
Leakage current is generated when reverse current rises to its maximum value in reverse-biased configuration of PN junction diode. This leakage current is independent of the applied reverse voltage.
Leakage current is affected to greater extent by the parameters of temperature, doping level and the physical size of junction. Sharp and sudden rise in leakage current can be observed in reverse bias characteristics due to excess of breakdown voltage, where the curve represents zero resistance at this point.
