BC849CLT1G 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; for the BC849 variant the emitter-base voltage rating is VEBO 5.0 Vdc per the Maximum Ratings table. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor, against which the BC849 collector-emitter voltage rating VCEO of 30 Vdc is specified. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor, rated for a continuous collector current of 100 mAdc and a BC849 collector-base voltage VCBO of 30 Vdc. |
