MMST3906 from BORN, 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 emitter-base voltage is limited to VEBO -5 V. |
| 2 | EMITTER | passive | Emitter terminal of the PNP transistor; the emitter-base voltage is limited to VEBO -5 V. |
| 3 | COLLECTOR | passive | Collector terminal of the PNP transistor; ratings are VCBO -50 V, VCEO -40 V and IC -200 mA continuous. |
