G1-MMBT5551

GOODWORK · Bipolar (BJT) · SOT-23

G1-MMBT5551 from GOODWORK, 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; the datasheet gives no separate pin-level limit, so the device ratings apply (VEBO 6 V, IC continuous 600 mA).
2 EMITTER passive Emitter terminal of the NPN transistor; the datasheet gives no separate pin-level limit, so the device ratings apply (VEBO 6 V, IC continuous 600 mA).
3 COLLECTOR passive Collector terminal of the NPN transistor; the datasheet gives no separate pin-level limit, so the device ratings apply (VCBO 180 V, VCEO 160 V, IC continuous 600 mA).

CAD (KiCad official)

  • Symbol: G1-MMBT5551
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: g1-mmbt5551-etched.step / g1-mmbt5551-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); g1-mmbt5551.step / g1-mmbt5551.glb are the bare package body.

Provenance

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

  • Datasheet: GOODWORK datasheet (5 pp, sha256 9fec2cdb671c19bc, 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).
