2N5401S from TECH PUBLIC, 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; emitter-base voltage limit is -6 V (VEBO) and DC gain hFE is 80 min at VCE=-5 V, IC=-1 mA. |
| 2 | Emitter | passive | Emitter of the PNP transistor; collector current is limited to -600 mA (IC) and total power dissipation to 300 mW. |
| 3 | Collector | passive | Collector of the PNP transistor; collector-base voltage limit is -180 V (VCBO) and collector-emitter voltage limit is -160 V (VCEO). |
