TMBT3904

TOSHIBA · Bipolar (BJT) · SOT-23

TMBT3904 from TOSHIBA, 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 input Base terminal of the NPN transistor, with base current IB rated to 30 mA maximum in the absolute maximum ratings.
2 Emitter passive Emitter terminal of the NPN transistor, with emitter-base voltage VEBO rated to 5 V maximum.
3 Collector passive Collector terminal of the NPN transistor, with collector-emitter voltage VCEO rated to 50 V and collector current IC rated to 150 mA maximum.

CAD (KiCad official)

  • Symbol: TMBT3904
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: tmbt3904-etched.step / tmbt3904-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmbt3904.step / tmbt3904.glb are the bare package body.

Provenance

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

  • Datasheet: TOSHIBA datasheet (5 pp, sha256 e9e449e9e2d1ddad, 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).
