MMBTSC1815G from ST Semtech, 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 of the NPN transistor; emitter-base voltage limited to 5 V (VEBO) and base current to 50 mA (IB). |
| 2 | Emitter | passive | Emitter of the NPN transistor; VCE(sat) is max 0.25 V at IC = 100 mA, IB = 10 mA. |
| 3 | Collector | passive | Collector of the NPN transistor; rated VCBO 60 V, VCEO 50 V and IC 150 mA. |
