So knowing this, with an NPN transistor, current needs to be sourced to the base of the transistor for operation. This means current needs to flow into the base. In a PNP transistor, current is sourced away or sinked from the base of the transistor to ground for operation. This means c...
Switch Capabilities: An NPN transistor can act as a switch, with the ability to turn on in saturation mode and off in cut-off mode. What is a NPN Transistor An NPN transistor is the most commonly used bipolar junction transistor, and is constructed by sandwiching a P-type semiconductor bet...
What is a transistor used for? Transistors are used within electronic circuits as microscopic on/off switches or to amplify signals. The availability of small, cheap transistors is one of the major advances that allowed for the computer revolution. How do PNP and NPN transistor differ? In the ...

PNP and NPN Transistors PNP and NPN transistors are opposite in their functionality. When you apply current to the Base Junction of the NPN transistor, it allows more power to flow through it; that’s why NPN are considered good for amplifiers. However, the PNP does the opposite. When you...
Fig. 4.6 shows a npn and a pnp transistor, the majority current flow in each, and the circuit symbol for each transistor. We will refer to this transistor as a bipolar junction transistor (BJT)—bipolar because holes and electrons are involved in its operation (although for the most part ...
What is a PNP Transistor? The term ‘PNP’ stands for positive, negative, positive, and also known as sourcing. The PNP transistor is a BJT; in this transistor, the letter ‘P’ specifies the polarity of the voltage necessary for the emitter terminal. The second letter ‘N’ specifies the...

PNP and NPN refer to thetransistor typesproviding the output voltage. The main difference between these two transistors is the direction of current. In the PNP sensor configuration, the wire providing the output signal will supply a positive outgoing current when energized. This is exactly what the...
