In PNP, transistor current is mainly due to

  1. Only holes.
  2. Only electrons.
  3. Mainly holes. 
  4. Mainly electrons.

Answer – C. Mainly holes.

In PNP, transistor current is mainly due to mainly holes.


In the PNP transistor, the emitter, heavily doped p-type, has the majority carrier as holes contributing to current as the base is lightly doped n-type where less recombination happens with the minority carrier electrons. So, the contributions to the collector current in PNP transistors are mainly due to holes.                

Therefore, the PNP transistor’s current is mainly due to holes.

Hence, Option (C) is the correct answer.
