MMBT3906W

GOODWORK · Bipolar (BJT) · SOT-323

MMBT3906W from GOODWORK, in a SOT-323. 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 passive Base terminal of the PNP transistor; the device-level absolute maximum emitter-base voltage -VEBO is 5 V and the emitter-base breakdown voltage is 5 V minimum at -IE = 10 µA.
2 EMITTER passive Emitter terminal of the PNP transistor; the absolute maximum emitter-base voltage -VEBO is 5 V and the absolute maximum collector current -IC is 200 mA.
3 COLLECTOR passive Collector terminal of the PNP transistor; the absolute maximum collector-emitter voltage -VCEO is 40 V and the absolute maximum collector current -IC is 200 mA.

CAD (KiCad official)

  • Symbol: MMBT3906W
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: mmbt3906w-etched.step / mmbt3906w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt3906w.step / mmbt3906w.glb are the bare package body.
