MMBT3904T-7-F-CN

Component

NPN transistorSOT-52340 V200 mA150 mW

MMBT3904T-7-F-CN is a 40 V, 200 mA NPN transistor in a compact SOT-523 package for low-power switching and small-signal amplification.

Best for

  • Low-power NPN switching
  • Small-signal amplifier stages
  • Space-constrained surface-mount designs

Avoid if

  • Collector current above 200 mA
  • Dissipation above 150 mW at 25 °C ambient
  • Applications requiring explicitly documented compliance or qualification status

Check before use

  • Confirm SOT-523 land pattern and orientation
  • Verify pin 1 base, pin 2 emitter, pin 3 collector
  • Derate power for ambient temperature
