SS8550S

FOSAN · Bipolar (BJT) · SOT-23

SS8550S 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 BASE input Base of the PNP transistor; VEBO is limited to -5 V and BVEBO is -5 V minimum at IE=-100uA.
2 EMITTER passive Emitter of the PNP transistor; VEBO rating is -5 V relative to the base.
3 COLLECTOR passive Collector of the PNP transistor; rated VCBO -40 V, VCEO -25 V and continuous collector current IC -1.5 A.

CAD (KiCad official)

  • Symbol: SS8550S
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: ss8550s-etched.step / ss8550s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ss8550s.step / ss8550s.glb are the bare package body.

Provenance

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

  • Datasheet: FOSAN datasheet (3 pp, sha256 ab17071b97a96670, 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.
