MMBT3906T7

Siliup · Bipolar (BJT) · SOT-723

MMBT3906T7 from Siliup, 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 PNP transistor; the datasheet gives VEBO of -5 V and an emitter-base breakdown voltage BVEBO of -5 V minimum.
2 EMITTER passive Emitter of the PNP transistor; the datasheet gives VEBO of -5 V as the maximum emitter-base voltage.
3 COLLECTOR passive Collector of the PNP transistor; the datasheet gives VCEO of -40 V, VCBO of -40 V and a collector current IC of -200 mA.

CAD (KiCad official)

  • Symbol: MMBT3906T7
  • Footprint: Package_TO_SOT_SMD:SOT-723
  • 3D model: SOT-723, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.5 mm nominal SOT-723 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: mmbt3906t7-etched.step / mmbt3906t7-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt3906t7.step / mmbt3906t7.glb are the bare package body.
