PNP transistor

P-N-P transistor:

  • The other type of BJT is the PNP, consisting of a P-doped semiconductor between two layers of P-doped material.
  • A small current leaving the base is amplified in the collector output.
  • A PNP transistor is ON when its based is pulled low relative to emitter.
