L2SC3837LT1G
LRC · Bipolar (BJT) · SOT-23
L2SC3837LT1G 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 | passive | Base terminal of the device; the datasheet gives the pin assignment only and states no separate base limit, with the device's maximum ratings being VCBO 30 V, VEBO 3 V and IC 50 mA. |
| 2 | EMITTER | passive | Emitter terminal; the emitter-base voltage is rated at a maximum of 3 V (VEBO) and the emitter cutoff current is at most 0.5 µA at VEB=2V. |
| 3 | COLLECTOR | passive | Collector terminal; rated for a maximum collector-base voltage of 30 V (VCBO), collector-emitter voltage of 18 V (VCEO) and collector current of 50 mA (IC). |
