Pnp Transistor Amplifier Circuit Diagram. The above figure shows the structure and symbol of pnp transistor. This is pnp and npn amplifier circuit diagram.
Amplification can be accomplished using vacuum tubes or semiconductor devices such as transistors or integrated circuits. Below is the circuit for connecting a pnp transistor which can function as a switch or an amplifier. 2sc5200 is npn transistor and 2sa1943 is pnp transistor.
The difference in the terminals is the direction in which the emitter arrow points.
This transistor mainly consists of 3 terminals and they are emitter e collector c and base b. 2sc5200 is npn transistor and 2sa1943 is pnp transistor. In both cases the arrow points from the p type material toward the n type material. Pnp transistors can also be used as switching devices and an example of a pnp transistor switch is shown below.
