BC817-16Q

Yangzhou Yangjie Elec Tech · Bipolar (BJT) · SOT-23

BC817-16Q from Yangzhou Yangjie Elec Tech, 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; drive current into the base to turn the device on, with VBE(sat) max 1.2 V at IC=500 mA, IB=50 mA.
2 E passive Emitter of the NPN transistor; emitter-base voltage VEBO is limited to 5 V.
3 C passive Collector of the NPN transistor; VCEO max 45 V, VCBO max 50 V, continuous IC max 500 mA.

CAD (KiCad official)

  • Symbol: BC817-16Q
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc817-16q-etched.step / bc817-16q-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc817-16q.step / bc817-16q.glb are the bare package body.
