LBC848ALT1G

LRC · Bipolar (BJT) · SOT-23

LBC848ALT1G 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 transistor; the LBC848 series is rated for an emitter-base voltage (VEBO) of 5.0 V maximum.
2 EMITTER passive Emitter terminal of the NPN transistor; the LBC848 series is rated for a collector-emitter voltage (VCEO) of 30 V and a collector-base voltage (VCBO) of 30 V.
3 COLLECTOR passive Collector terminal of the NPN transistor; the LBC848 series is rated for a continuous collector current (IC) of 100 mA maximum.
