MMBT4401LT1G from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BASE | input | Base terminal of the NPN BJT. Emitter-base breakdown voltage VEBO = 6.0 V; VBE(sat) up to 0.95 V at IC = 150 mA, IB = 15 mA. |
| 2 | EMITTER | passive | Emitter terminal of the NPN BJT. Common return for base-emitter and collector-emitter junctions; VCEO = 40 V, VEBO = 6.0 V. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN BJT. VCBO = 60 V, VCEO = 40 V, continuous IC = 600 mA (peak 900 mA); VCE(sat) 0.4 V @ IC = 150 mA. |
