Working Principle of 2N4401_J05Z

The working principle of 2N4401_J05Z is based on its internal structure. It is made of two p-type and one n-type semiconductor layers placed adjacent to each other. The n-type layer has a negative charge, and the p-type layers has a positive charge. When an input current flows through the base-emitter junction, it triggers an internal electric field which causes current to be generated in the collector-emitter junction. This current is known as the collector current. As the collector current increases, the collector-emitter voltage decreases, resulting in a negative resistance effect. The voltage and current at the collector terminal can then be adjusted using a variable resistor.
