# LMUN2116LT1G

**LRC** · Digital Transistors · SOT-23

LMUN2116LT1G 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 (INPUT) terminal of the BRT, which connects to the monolithic bias network of a series base resistor and a base-emitter resistor. |
| 2 | EMITTER | power_in | Emitter terminal, labelled GROUND in the datasheet, serving as the reference for the base-emitter bias resistor. |
| 3 | COLLECTOR | output | Collector (OUTPUT) terminal, rated for a collector-emitter voltage VCEO of 50 Vdc and a collector current IC of 100 mAdc. |

## CAD (KiCad official)

- Symbol: `LMUN2116LT1G`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `lmun2116lt1g-etched.step` / `lmun2116lt1g-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lmun2116lt1g.step` / `lmun2116lt1g.glb` are the bare package body.
