BC817-25W

Nexperia · Bipolar (BJT) · SOT-323

BC817-25W from Nexperia, in a SOT-323. 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 passive Base terminal of the NPN transistor; the datasheet gives no separate electrical limits for this pin beyond the device limiting values.
2 E passive Emitter terminal of the NPN transistor; the datasheet gives no separate electrical limits for this pin beyond the device limiting values.
3 C passive Collector terminal of the NPN transistor; the datasheet gives no separate electrical limits for this pin beyond the device limiting values.

CAD (KiCad official)

  • Symbol: BC817-25W
  • Footprint: Package_TO_SOT_SMD:SOT-323_SC-70
  • 3D model: SOT-323 (KiCad packages3D, STEP)
  • 3D model files: bc817-25w-etched.step / bc817-25w-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc817-25w.step / bc817-25w.glb are the bare package body.

Provenance

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

  • Datasheet: Nexperia datasheet (13 pp, sha256 d9aba599bcbb8819, 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).
