MMBT3906M

TECH PUBLIC · MOSFETs · SOT-723

MMBT3906M 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 PNP transistor; the datasheet rates emitter-base voltage at -5 V (VEBO) and breakdown V(BR)EBO at -5 V min.
2 Emitter passive Emitter of the PNP transistor; continuous collector current is rated at -0.2 A and power dissipation at 100 mW.
3 Collector passive Collector of the PNP transistor; collector-base and collector-emitter voltages are each rated at -40 V.

Package SOT-723
Category Transistors/Thyristors
Pins 3

CAD (KiCad official)

  • Symbol: MMBT3906M
  • 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: mmbt3906m-etched.step / mmbt3906m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt3906m.step / mmbt3906m.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: TECH PUBLIC datasheet (4 pp, sha256 230915d3e3d54dcf, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
