MMBTSC3875L from PJSEMI, 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 terminal of the NPN transistor; emitter-base voltage rating VEBO is 5 V and emitter-base cutoff current IEBO is at most 100 nA at VEB = 5 V. |
| 2 | Emitter | passive | Emitter terminal of the NPN transistor; the device is rated for a collector current IC of 150 mA maximum. |
| 3 | Collector | passive | Collector terminal of the NPN transistor; rated for VCBO of 60 V and VCEO of 50 V, with collector current IC up to 150 mA. |
