Pnp Schaltung. Grundsätzlich sollte im i b und im i c stromkreis ein strombegrenzender widerstand eingesetzt sein. 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.
Pnp is also known as sourcing pnp devices switch the positive side of the circuit. An npn device sinks or provides 24 v to the input card when active. The construction and terminal voltages for an npn transistor are shown above.
Pnp darlington transistor features this device is designed for applications reguiring extremely high current gain at currents to 1 a.
Ein npn typ in emitterschaltung richtig. Pnp transistor as a switch. Das ergibt sich aus der anordnung der bauteile in deiner schaltung. The circuit in the above figure shows the pnp transistor as a switch.
