And as you decrease voltage to the base of a NPN transistor, the transistor turns on less and less, until the voltage is so low, the transistor no longer conducts across emitter to collector, and shuts off.When you increase voltage to the base of a NPN transistor, the transistor is turned on more and more until it conducts fully from emitter to collector.A NPN transistor conducts from emitter to collector.And as you decrease voltage to the base of a PNP transistor, the transistor turns on more and more, until the transistor fully conducts from collector to emitter.When you increase voltage to the base of a PNP transistor, the transistor is turned off more and more until it no longer conducts and completely shuts off.A PNP transistor conducts from collector to emitter.The difference between a PNP transistor and a NPN transistor is their polarity and their actions are reversed… PNP Transistor (you should see my project after reading this post) These back to back PN junction diodes are. The PNP transistor behaves like two PN junctions diodes connected back to back. A PNP transistor has three terminals a Collector (C), Emitter (E) and Base (B). I’ve decided to write this post to support a bit of the theory behind my new project that identifies the PNP and NPN transistors easily. In a NPN, it takes positive voltage on the base relative to E or C to make the diodes conduct, and the other way around with a PNP. A PNP transistor is a bipolar junction transistor constructed by sandwiching an N-type semiconductor between two P-type semiconductors. ![]()
