First, the classification of leakage current
Generally, there are four types of leakage currents: semiconductor component leakage current, power supply leakage current, capacitor leakage current and filter leakage current.
1. Leakage current of semiconductor components
The very small current that flows through the PN junction when it is turned off. D-S is forward biased, G-S is reverse biased, and after the conductive channel is opened, current will flow from D to S. But in fact, due to the existence of free electrons, free electrons are attached to SIO2 and N+, re...
