S8550

hongjiacheng · Bipolar (BJT) · SOT-23

S8550 from hongjiacheng, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 B input Base terminal for PNP transistor control with maximum emitter-base breakdown voltage V(BR)EBO = -5.0V.
2 E passive Emitter terminal with maximum emitter-base voltage VEBO = -5.0V for PNP transistor operation.
3 C passive Collector terminal with maximum ratings VCBO = -40V, VCEO = -25V, IC = -0.5A, and power dissipation 300mW.

CAD (KiCad official)

  • Symbol: S8550
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: s8550-etched.step / s8550-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); s8550.step / s8550.glb are the bare package body.
