PNP Transistor Tutorial - The Bipolar PNP Transistor
2024年7月14日 · Generally, the PNP transistor can replace NPN transistors in most electronic circuits, the only difference is the polarities of the voltages, and the directions of the current flow. PNP transistors can also be used as switching devices and an example of a PNP transistor switch is shown below.
PNP Transistor – How Does It Work? - Build Electronic Circuits
2016年12月19日 · Let’s see how to create a simple PNP transistor circuit. With this circuit, you can turn on a light-emitting diode (LED) when it gets dark. Step 1: The Emitter. First of all, to turn on the PNP transistor, you need the voltage on the base to be lower than the emitter. For a simple circuit like this, it’s common to connect the emitter to the ...
PNP Transistor: How Does it Work? (Symbol & Working …
2020年3月25日 · A PNP transistor is a bipolar junction transistor constructed by sandwiching an N-type semiconductor between two P-type semiconductors. A PNP transistor has three terminals – a Collector (C), Emitter (E) and Base (B). The PNP transistor behaves like two PN junctions diodes connected back to back.
