Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | Base | input | Base input pin. Drives the NPN transistor through the monolithic series bias resistor R1 = 4.7 kΩ; R2 = 47 kΩ sits between the internal base node and the emitter. Input high turns the transistor on. |+| 2 | Emitter | passive | Emitter of the internal NPN transistor. Typically tied to circuit ground / signal return. |+| 3 | Collector | output | Open-collector output of the internal NPN transistor. Typically pulled up to a supply through the load; IC up to 100 mA, VCEO = 50 V max. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LRC |+| Package | SOT-23 |+| Category | Transistors/Thyristors |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `LMUN2233LT1G`+- `LMUN2233LT1GLT3G`++## CAD (KiCad official)++- Symbol: `LMUN2233LT1G`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LRC datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8586172813665849344) (16 pp, sha256 `7a7fc5dcf748e5bd`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
