BC817-16LT3G

onsemi · Bipolar (BJT) · SOT-23

BC817-16LT3G from onsemi, 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 BASE input Base terminal of the NPN transistor; the datasheet rates the emitter-base voltage (VEBO) at 5.0 V maximum.
2 EMITTER passive Emitter terminal of the NPN transistor; the datasheet rates the emitter-base voltage (VEBO) at 5.0 V maximum.
3 COLLECTOR passive Collector terminal of the NPN transistor; the datasheet rates the collector-emitter voltage (VCEO) at 45 V and the continuous collector current (IC) at 500 mA.

CAD (KiCad official)

  • Symbol: BC817-16LT3G
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: bc817-16lt3g-etched.step / bc817-16lt3g-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); bc817-16lt3g.step / bc817-16lt3g.glb are the bare package body.
