Recommended Reading: PNP Vs NPN: What Makes These Outputs Different
This is an excerpt from a recent educational article by Banner: The difference between PNP and NPN is the construction of the semiconducting material found inside the transistor. In a PNP transistor, the semiconducting material is made of three layers: a negative (N) layer between two positive (P) layers: Positive-Negative-Positive, or PNP. Likewise, an NPN…
