L9012RLT1G from LRC, 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 PNP general-purpose transistor; the emitter cutoff current IEBO is specified at VBE = -4 V with a maximum of -150 nA. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the emitter-base breakdown voltage V(BR)EBO is listed in the datasheet, but its value is not legible in the extracted text. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor, rated for VCEO -20 V, VCBO -40 V and continuous collector current IC -500 mA. |
