MMBT3904M

TECH PUBLIC · Bipolar (BJT) · SOT-723

MMBT3904M from TECH PUBLIC, in a SOT-723. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BASE input Base of the NPN transistor; Emitter-Base voltage max 6 V (VEBO) and V(BR)EBO min 6 V at IE=10µA.
2 EMITTER passive Emitter of the NPN transistor; collector current continuous max 0.2 A (IC).
3 COLLECTOR passive Collector of the NPN transistor; VCBO 60 V, VCEO 40 V, continuous collector current 0.2 A max.

CAD (KiCad official)

  • Symbol: MMBT3904M
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723 (KiCad packages3D, STEP)
  • 3D model files: mmbt3904m-etched.step / mmbt3904m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt3904m.step / mmbt3904m.glb are the bare package body.
