LBC846BLT1G from LRC, 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 silicon transistor; the datasheet's emitter-base voltage rating VEBO is 6.0 V for LBC846 and LBC847/LBC850 and 5.0 V for LBC848/LBC849. |
| 2 | EMITTER | passive | Emitter terminal of the NPN silicon transistor; continuous collector current IC is rated at 100 mAdc maximum. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN silicon transistor; collector-emitter voltage VCEO is rated 65 Vdc for LBC846, 45 Vdc for LBC847/LBC850 and 30 Vdc for LBC848/LBC849. |
