MMBT2907A

TWGMC · Bipolar (BJT) · SOT-23

MMBT2907A from TWGMC, in a SOT-23. 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 B input Base terminal of the PNP transistor; the datasheet limits the emitter-base voltage VEBO to -5 V.
2 E passive Emitter terminal of the PNP transistor; the emitter-base breakdown voltage V(BR)EBO is -5 V at IE=-10μA.
3 C passive Collector terminal of the PNP transistor; the datasheet limits collector current to -600 mA continuous and collector-emitter voltage VCEO to -60 V.

CAD (KiCad official)

  • Symbol: MMBT2907A
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbt2907a-etched.step / mmbt2907a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt2907a.step / mmbt2907a.glb are the bare package body.
