MMBT3906LT1

LGE · Bipolar (BJT) · SOT-23

MMBT3906LT1 from LGE, 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 BASE passive Base terminal of the PNP transistor; the datasheet's peak base current limit is IBM = -100 mA.
2 EMITTER passive Emitter terminal of the PNP transistor; the emitter-base voltage limit is VEBO = -6 V (emitter-base voltage with open collector).
3 COLLECTOR passive Collector terminal of the PNP transistor; the datasheet limits are VCEO = -40 V (open base), DC collector current IC = -100 mA, and peak collector current ICM = -200 mA.

CAD (KiCad official)

  • Symbol: MMBT3906LT1
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbt3906lt1-etched.step / mmbt3906lt1-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt3906lt1.step / mmbt3906lt1.glb are the bare package body.

Provenance

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

  • Datasheet: LGE datasheet (3 pp, sha256 cd898b24bba5e6d6, retrieved 2026-10-09, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-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).
