MMBT3906M from TECH PUBLIC, in a SOT-723. 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 PNP transistor; the datasheet rates emitter-base voltage at -5 V (VEBO) and breakdown V(BR)EBO at -5 V min. |
| 2 | Emitter | passive | Emitter of the PNP transistor; continuous collector current is rated at -0.2 A and power dissipation at 100 mW. |
| 3 | Collector | passive | Collector of the PNP transistor; collector-base and collector-emitter voltages are each rated at -40 V. |
