MMBT2222A-6AF

FOSAN · Bipolar (BJT) · SOT-23

MMBT2222A-6AF from FOSAN, 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 B input Base of the NPN transistor; emitter-base voltage is limited to 6 V (VEBO) and BVEBO is 6 V min at IE=10 µA.
2 E passive Emitter of the NPN transistor; emitter-base voltage is limited to 6 V (VEBO).
3 C passive Collector of the NPN transistor, rated 600 mA continuous (IC), VCEO 60 V and VCBO 75 V for the MMBT2222A-6AF.

CAD (KiCad official)

  • Symbol: MMBT2222A-6AF
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: mmbt2222a-6af-etched.step / mmbt2222a-6af-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mmbt2222a-6af.step / mmbt2222a-6af.glb are the bare package body.

Provenance

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

  • Datasheet: FOSAN datasheet (4 pp, sha256 ec4ad70050a6c326, retrieved 2026-10-09, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+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.
