Um den PNP-Transistor als Schalter „ON“ zu schalten, wird die Basisklemme wie abgebildet mit Masse oder Null Volt (LOW) verbunden. However, if the emitter current is 1mA, then collector current is also about 1mA. This is precisely what happens in a transistor.

The word Transistor is a combination of the two words Trans fer Var istor which describes their mode of operation way back in their early days of electronics development. There are two basic types of bipolar transistor construction, PNP and NPN, which basically describes the physical arrangement of the P-type and N-type semiconductor materials from which they are made. PNP-Transistoren werden über einen negativen Strom an der Basis angesteuert, um den Stromfluss vom Emitter zum Kollektor zu steuern. (Beachten Sie, dass die Polarität beim PNP-Transistor im Vergleich zum NPN-Transistor umgekehrt ist.) Weitere Informationen können Sie Abbildung 4 unten entnehmen.
Prinzipiell arbeitet ein pnp Transistor genauso wie ein npn Transistor. Aber da die Zonenfolge anders ist, d.h. Emitter, Basis und Kollektor sind gegenüber dem npn Transistor entgegengesetzt dotiert, fließt der Strom also mittels anderer Ladungsträger! Die Majoritätsträger im pnp Transistor sind die Elektronenlöcher. Aber um diese Löcherleitung überhaupt zu ermöglichen, müssen auch ... PNP Transistor Tutorial - The Bipolar PNP Transistor. Posted: (2 days ago) 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.
