Applications of NPN transistor

NPN transistor with their function in amplifying currents they have many applications and between PNP and NPN, the only difference is the direction of voltage flow.

Let we check the applications of NPN transistor :
  • Mostly used in switching applications.
  • Used in applications where there is a need to sink current.
  • Used in amplifying circuit applications, such as push-pull amplifier circuits. 
  • It is used to amplify weak signals in the Darlington pair circuits. 
  • Used in temperature sensors. 
  • Used in very high-frequency applications.
  • Used in logarithmic converters.
