A Bipolar Junction Transistor  is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
  • Two types of BJTs, the NPN and PNP 
  • The two junctions are termed the base-emitter junction and the base-collector junction 
  • In order for the transistor to operate properly, the two junctions must have the correct dc bias voltage
  •        – the base-emitter (BE) junction is forward biased
  •        – the base-collector (BC) junction is reverse biased
  • Package-Type:  SOT23 / TO-92
  • Polarity: PNP / NPN
  • Number of Pins: 3


  • Width: 2cm 
  • Length: 2 cm
  • Depth: 2 cm
