Pnp Transistor Schaltbild. These back to back pn junction diodes are known as the collector base. 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.
Der pnp transistor besteht aus zwei p leitenden schichten. The output characteristics curves for a pnp transistor look very similar to those for an equivalent npn transistor except that they are rotated by 180 o to take account of the reverse polarity voltages and currents that is for a pnp transistor electron current flows out of the base and collector towards the battery. The same dynamic load line can be drawn onto the i v curves to find the pnp transistors operating points.
A pnp transistor receives positive voltage to the emitter terminal and a negative voltage at the base terminal or rather a more negative or lower voltage than what is supplied at the emitter terminal.
Dazwischen liegt eine dünne n leitende schicht. The structure of the pnp transistor is completely different from the npn transistor. The output characteristics curves for a pnp transistor look very similar to those for an equivalent npn transistor except that they are rotated by 180 o to take account of the reverse polarity voltages and currents that is for a pnp transistor electron current flows out of the base and collector towards the battery.
