MMBT3906W from GOODWORK, in a SOT-323. 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 PNP transistor; the device-level absolute maximum emitter-base voltage -VEBO is 5 V and the emitter-base breakdown voltage is 5 V minimum at -IE = 10 µA. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the absolute maximum emitter-base voltage -VEBO is 5 V and the absolute maximum collector current -IC is 200 mA. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; the absolute maximum collector-emitter voltage -VCEO is 40 V and the absolute maximum collector current -IC is 200 mA. |
