In a pnp transistor working as a common base
WebAug 25, 2024 · In normal conditions when the NPN transistor emitter is at GND and the load at the collector side. The collector current can only flow from "collector to emitter". The collector can only "sink" current. But if we put a load between the emitter and GND and collector to the power supply. WebApr 8, 2024 · The current inside a PNP transistor moves from the emitter to the collector through the holes while it flows through the electrons in the outer circuit. Transistor has two p-n junctions, Base-emitter (BE) and Base collector (BC) junction. By biasing these two junctions in different ways, different functions can be taken from the same transistor.

WebDec 8, 2024 · A transistor has three zones; emitter, base and collector, and can be built two different ways, as NPN or PNP. An NPN transistor has an N doped emitter, a P-doped base followed by an N-doped collector as shown in Figure 1a) and represented schematically in Figure 1b). Not surprisingly then, A PNP transistor has P doped emitter and an N-doped ... WebSep 7, 2024 · A PNP Bipolar Junction Transistor has an N-doped semiconductor base in between a P-doped emitter and P-doped collector region. The PNP Transistor has very similar characteristics to the NPN Transistor, with the difference being the biasing of the current and voltage directions are reversed.
