Application Scenarios & Design Considerations

NPN (MEDIUM POWER AMPLIFIER LOW SATURATION)

Alternative Part Number

  • 2N3904 --: Widely available NPN general-purpose transistor with similar small-signal switching characteristics and pinout, easy drop-in for many KSC2500 applications.
  • BC547 --: Popular NPN transistor with comparable current gain and voltage ratings, suitable for general switching and amplification where KSC2500 is used.
  • MMBT3904 --: SMD version of the 2N3904 with similar electrical performance, good choice when a surface-mount alternative to the KSC2500 is acceptable.
