MMBT3906TT1G

onsemi · Bipolar (BJT) · SOT-416

MMBT3906TT1G from onsemi, in a SOT-416. 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 terminal of the PNP general-purpose amplifier; the datasheet specifies base cutoff current IBL at 50 nAdc maximum for VCE = −30 Vdc and VEB = −3.0 Vdc.
2 EMITTER passive Emitter terminal of the PNP amplifier; the emitter-base voltage rating is VEBO = −5.0 Vdc and the emitter-base breakdown voltage V(BR)EBO is −5.0 Vdc minimum.
3 COLLECTOR passive Collector terminal of the PNP amplifier; the datasheet rates VCEO and VCBO at −40 Vdc and continuous collector current IC at −200 mAdc.

CAD (KiCad official)

  • Symbol: MMBT3906TT1G
  • Footprint: Package_TO_SOT_SMD:SOT-416
  • 3D model: SOT-416, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: mmbt3906tt1g-etched.step / mmbt3906tt1g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt3906tt1g.step / mmbt3906tt1g.glb are the bare package body.
