Application Scenarios & Design Considerations

NPN silicon switching transistor

Alternative Part Number

  • MMBT3904 --: Industry-standard NPN small-signal transistor with the same 3904 die characteristics and SOT-23 package, widely available and a direct functional replacement.
  • 2N3904 --: Classic through-hole NPN general-purpose transistor with equivalent electrical ratings; suitable if the PCB allows a TO-92 package or for prototyping.
  • BC847 --: SOT-23 NPN transistor with comparable voltage and current ratings, a common European-market substitute when exact 3904 characteristics are not critical.
