# LBC846ALT1G

**LRC** · Bipolar (BJT) · SOT-23

LBC846ALT1G 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 NPN transistor, which is rated for a continuous collector current of 100 mA and an emitter-base voltage of 6.0 V (LBC846/LBC847/LBC850) or 5.0 V (LBC848/LBC849) maximum. |
| 2 | EMITTER | passive | Emitter terminal of the NPN transistor, with emitter-base breakdown V(BR)EBO of at least 6.0 V for LBC846/LBC847/LBC850 and 5.0 V for LBC848/LBC849. |
| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor, with collector-emitter voltage VCEO rated up to 65 V (LBC846) and continuous collector current up to 100 mA. |
