LMBTA14LT1G 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 Darlington pair; the datasheet gives no separate base current limit, only the 10 Vdc emitter-base voltage rating (VEBO) and the 300 mAdc continuous collector current rating. |
| 2 | EMITTER | passive | Emitter terminal; the datasheet rates the emitter-base voltage at 10 Vdc maximum (VEBO) and the device at 300 mAdc continuous collector current. |
| 3 | COLLECTOR | passive | Collector terminal; the datasheet rates collector-emitter voltage at 30 Vdc (VCES), collector-base voltage at 30 Vdc (VCBO) and continuous collector current at 300 mAdc. |
