Application Scenarios & Design Considerations

NPN Epitaxial Silicon Darlington Transistor

Alternative Part Number

  • 2N3904 --: Widely available NPN small-signal transistor in TO-92, similar switching and amplification role; pinout and general specs make it a practical drop-in for many KSP14 applications.
  • BC547 --: Popular NPN general-purpose transistor in TO-92 with comparable current and voltage ratings, suitable for low-power switching and amplification.
  • MMBT3904 --: SMD version of the 2N3904 NPN transistor, offering equivalent small-signal performance for designs that can use surface-mount packages.
