BC847A

Nexperia · Bipolar (BJT) · SOT-23

BC847A from Nexperia, 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; NPN transistor control input with DC current gain hFE = 110-220 at VCE = 5 V and IC = 2 mA
2 E passive Emitter; NPN transistor emitter terminal
3 C passive Collector; NPN transistor collector terminal with maximum rating IC = 100 mA and VCEO = 45 V

CAD (KiCad official)

  • Symbol: BC847A
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc847a-etched.step / bc847a-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc847a.step / bc847a.glb are the bare package body.
