Question
In a PNP transistor, the base is of________ material.
The correct answer is
N
PNP Transistor Base Material Identification
A PNP transistor consists of three semiconductor layers. The structure is defined by the types of materials used for the Emitter, Base, and Collector regions.
- P in PNP refers to the P-type semiconductor material used for the Emitter.
- N in PNP refers to the N-type semiconductor material used for the Base.
- The final P refers to the P-type semiconductor material used for the Collector.
Therefore, the base layer in a PNP transistor is made of N-type semiconductor material.
The correct option is N.
