MMBT2907AT from YFW, in a SOT-523. 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 transistor; the datasheet gives emitter-base breakdown voltage VEBO of -5 V and emitter cut-off current IEBO of -100 nA at VEB = -5 V. |
| 2 | Emitter | passive | Emitter terminal of the PNP transistor; the datasheet limits emitter-base voltage to -5 V (VEBO) and gives emitter input capacitance Cib of 30 pF at VEB = -2 V. |
| 3 | Collector | passive | Collector terminal of the PNP transistor; the datasheet rates collector-base voltage VCBO at -60 V, collector-emitter voltage VCEO at -60 V and continuous collector current IC at -600 mA. |
