BC817-25

FUXINSEMI · Bipolar (BJT) · SOT-23

BC817-25 from FUXINSEMI, 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; the datasheet pinning table lists it as Base, drawn at the bottom left of the outline.
2 E passive Emitter of the NPN transistor; the datasheet lists it as Emitter, drawn at the bottom right. VEBO is 5 V maximum.
3 C passive Collector of the NPN transistor; the datasheet lists it as Collector, drawn at the top. VCBO is 50 V, VCEO is 45 V and IC is 500 mA maximum.

CAD (KiCad official)

  • Symbol: BC817-25
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc817-25-etched.step / bc817-25-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc817-25.step / bc817-25.glb are the bare package body.
