2SC945M-P from Foshan Blue Rocket Elec, 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, with a continuous base current rating IB of 20 mA. |
| 2 | Emitter | passive | Emitter terminal of the NPN transistor, with an emitter-to-base voltage rating VEBO of 5.0 V. |
| 3 | Collector | passive | Collector terminal of the NPN transistor, rated for 50 V collector-to-emitter (VCEO), 150 mA continuous collector current (IC) and 250 mW collector power dissipation (PC). |
