Pnp Transistor Schaltplan. It s one of the transistors that james lewis recommends in his article on the best 4 transistors to keep in your parts kit. Tut der pfeil der basis weh handelt s sich um pnp.
The positive voltage to the emitter allows current to flow from the emitter to the collector given that there is negative current to the base current flowing out of the base to ground. A reduction in the gain of the pnp transistor increases the igbt on state voltage drop. Consider a pnp transistor which is connected in the circuit with the supply voltages v b 1 5v v e 2v v cc 10v and v cc 10v.

Consider a pnp transistor which is connected in the circuit with the supply voltages v b 1 5v v e 2v v cc 10v and v cc 10v. The pnp transistor has very similar characteristics to their npn bipolar cousins except that the polarities or biasing of the current and voltage directions are reversed for any one of the possible three configurations looked at in the first tutorial common base common emitter and common collector. The transistor i used in this video is a bc557 pnp transistor. The photoresistor i used has about 10 kω when it s light and 1 mω when it s dark.
