# L2SC1623SLT1G

**LRC** · Bipolar (BJT) · SOT-23

L2SC1623SLT1G 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 transistor; the datasheet gives the Base-Emitter saturation voltage (VBE(sat) max 1.0 V at IC=100 mA, IB=10 mA) and Base-Emitter voltage (VBE 0.55 to 0.65 V at IC=1 mA, VCE=6 V) for this pin's operating conditions. |
| 2 | EMITTER | passive | Emitter terminal of the transistor; the datasheet's maximum emitter-base voltage is VEBO 7 V and the emitter cutoff current is specified at VEB=5 V. |
| 3 | COLLECTOR | passive | Collector terminal of the transistor; the datasheet's maximum ratings are VCEO 50 V, VCBO 60 V and collector current IC 150 mA continuous. |
