**LRC** · Bipolar (BJT) · SOT-883

LBC847BN3T5G from LRC, in a SOT-883. 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 current or voltage limit beyond the device maximum ratings (VCEO 45 V, VCBO 50 V, VEBO 6 V, IC 100 mA continuous at Ta = 25 ºC). |
| 2 | EMITTER | passive | Emitter terminal of the NPN general-purpose transistor; the datasheet gives no pin-specific limit beyond the device maximum ratings (VEBO 6 V, IC 100 mA continuous at Ta = 25 ºC). |
| 3 | COLLECTOR | passive | Collector terminal of the NPN general-purpose transistor; the datasheet gives no pin-specific limit beyond the device maximum ratings (VCEO 45 V, VCBO 50 V, IC 100 mA continuous at Ta = 25 ºC). |

## CAD (KiCad official)

- Symbol: `LBC847BN3T5G`
- Footprint: `Package_TO_SOT_SMD:SOT-883`
- 3D model: SOT-883, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.45 mm nominal SOT height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `lbc847bn3t5g-etched.step` / `lbc847bn3t5g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lbc847bn3t5g.step` / `lbc847bn3t5g.glb` are the bare package body.
