  • Don't really need to know PNP
  • PNP is basically the same as NPN

    • NPN BJTs enable faster switching because n-type semiconductor can transfer electrons significantly faster than p-type semiconductor can transfer positive electron holes (electrons have greater mobility than electron holes)
    • NPN BJTs are more commonly used in the industry (in Asia)
    • Whether to use NPN or PNP depends on the circuit it is connected to (will the BJT need to sink or source current)
