MMBT3906M-JSM

JSMSEMI · Bipolar (BJT) · SOT-723

MMBT3906M-JSM from JSMSEMI, 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 terminal of the PNP transistor; emitter-base breakdown voltage V(BR)EBO is -5 V minimum and the maximum VEBO rating is -5 V.
2 EMITTER passive Emitter terminal of the PNP transistor; continuous collector current is rated at -0.2 A maximum.
3 COLLECTOR passive Collector terminal of the PNP transistor; collector-base and collector-emitter voltages are rated at -40 V maximum, with 100 mW power dissipation.

CAD (KiCad official)

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

Provenance

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

  • Datasheet: JSMSEMI datasheet (3 pp, sha256 52966cd3c1dbda55, retrieved 2026-10-27, 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).
