The above figure shows the schematic and circuit diagram of the PNP transistor. The above figure shows that the base terminal is always positive with respect to the emitter, and voltage VBEis applied between the base and emitter: In the above figure, the emitter is connected to VCCwith respec...

I was wondering is someone can explain in practical terms what the difference between a npn and pnp transistor is. When would I use one over the other? My original understanding is pnp are ‘normally closed’ and npn’s are normally open. After playing around with some, I find that isn’...
The name PNP goes along with the similarly named PNP bipolar junction transistor. In a PNP transistor, current is sent into the emitter pin, and out through the base and collector. When current flows through the base pin, a much larger current is allowed to flow through the collector. In ...
PNP or NPN ?In three simple steps . Learn if the transistor is PNP or NPN . . . and learn to identify the collector , base and emitter . . . How many times have you looked for a transistor used in the table and wanted to know their characteristics , and identification of ...
Transistor QN2 is normally in cut-off conditions, that is not conducting, because of the large voltage difference existing across its base and its collector. If the PNP transistor, QP1, enters the saturation zone (for example upon a sudden increase of the load impedance) the sudden fall of...
For example, if the device has a cathode ring around the anode region, the base resistance and thus the effective gain of bipolar transistor B will be much lower than in a case where the device has a circular geometry with the cathode (comprising layers 110, 122, 108) in the center. ...
