MMBT4401LT1G-CN

Bipolar Transistors - BJT

NPNSOT-2340 V600 mAswitching transistor

MMBT4401LT1G-CN is a 3-pin SOT-23 NPN switching transistor for low- and medium-current switching stages up to 40 V VCEO and 600 mA continuous collector current.

Best for

  • General-purpose NPN switching
  • Low-side switching stages
  • Compact SOT-23 transistor circuits

Avoid if

  • Collector-emitter voltage exceeds 40 V
  • Continuous collector current exceeds 600 mA
  • The design requires stated automotive, RoHS, REACH, or MSL qualification

Check before use

  • Base-drive current at the required collector current
  • Saturation voltage and switching-loss budget
  • PCB thermal layout and ambient-temperature derating
  • Compliance and lifecycle requirements
