C1815

Changjing · Bipolar (BJT) · SOT-23

C1815 from Changjing, 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 passive Base terminal of the NPN transistor; the datasheet gives no pin-specific limit, and the device-level maximum ratings are VCBO 60 V, VCEO 50 V, VEBO 5 V, IC 150 mA continuous and PC 200 mW.
2 EMITTER passive Emitter terminal of the NPN transistor; the datasheet gives no pin-specific limit, and the emitter-base reverse limit is VEBO 5 V.
3 COLLECTOR passive Collector terminal of the NPN transistor; the datasheet gives no pin-specific limit, and the collector ratings are VCBO 60 V, VCEO 50 V and IC 150 mA continuous.

CAD (KiCad official)

  • Symbol: C1815
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: c1815-etched.step / c1815-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); c1815.step / c1815.glb are the bare package body.
