BC817-QR

Nexperia · Bipolar (BJT) · SOT-23

BC817-QR from Nexperia, 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; peak base current is limited to 200 mA (single pulse, tp ≤ 1 ms, Tamb = 25 °C).
2 E passive Emitter of the NPN transistor; emitter-base voltage is limited to 5 V (VEBO, open collector, Tamb = 25 °C).
3 C passive Collector of the NPN transistor; collector-emitter voltage is limited to 45 V (VCEO), collector current to 500 mA, and peak collector current to 1 A (single pulse, tp ≤ 1 ms).

CAD (KiCad official)

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