**LRC** · Bipolar (BJT) · SOT-23

L9014QLT1G 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 general-purpose transistor; the datasheet gives no pin-specific limit for this pin, only device maximum ratings such as Emitter-Base Voltage VEBO 5 V and Collector current IC 100 mA. |
| 2 | EMITTER | passive | Emitter terminal of the NPN general-purpose transistor; the datasheet gives no pin-specific limit for this pin, only device maximum ratings such as Emitter-Base Voltage VEBO 5 V and Collector current IC 100 mA. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN general-purpose transistor; the datasheet gives no pin-specific limit for this pin, only device maximum ratings such as Collector-Emitter Voltage VCEO 45 V and Collector-Base Voltage VCBO 50 V. |
