PNP-transistor works as a switch: The Emitter potential for aPNPtransistor needs to be positive with respect to the Base. The transistor then functions as a solid-state "single-pole single-throw"(SPST)switch. The transistor becomes "OFF," operating like an open switch when a zero signal is...
When a small current flows from the base (B) of the transistor, it is switched on and behaves like a closed circuit. The base is always negative as compared to the collector and emitter terminals. The electrons flow from the base and the current entering the base is amplified before reachi...
Inthis state, the PNP transistor acts like an open switch, allowing no current to flow through it. For example, imagine a PNP transistor in a circuit where the base-emitter junction is not forward biased. In this case, the transistor will be in cutoffmode, and the collector voltage will ...

A circuit is provided for reducing the turn-off transition time of a switching PNP transistor by providing a reverse drive current to the base of the PNP transistor after the drive current has been removed from the base. The reverse drive current is generated by an NPN transistor, the emitter...
