MMBT3904T

Transistors - Bipolar (BJT) - Single

NPNBJTSOT-523Transistor

The MMBT3904T is a standard NPN BJT in an SOT-523 package, ideal for general-purpose signal amplification and switching in space-constrained designs.

Best for

  • Low-power signal switching
  • Small-signal amplification
  • Space-constrained PCB designs

Avoid if

  • High-power applications exceeding 150mW
  • High-current switching above 200mA

Check before use

  • Thermal dissipation requirements
  • hFE range at your specific collector current
