AD-MMBT5401-H from Changjing, 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 of the PNP transistor; VEBO is limited to -5 V and IEBO is at most -100 nA at VEB = -4 V. |
| 2 | EMITTER | passive | Emitter of the PNP transistor; the emitter-base breakdown voltage V(BR)EBO is at least -5 V at IE = -10 µA. |
| 3 | COLLECTOR | passive | Collector of the PNP transistor; VCBO is -160 V, VCEO is -150 V and continuous collector current IC is -0.6 A. |
