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. Connected through the internal 4.7 kΩ series resistor R1 to the transistor base; a second 4.7 kΩ resistor R2 shunts base-to-emitter. Drive with a logic-level signal to switch the transistor on. |+| 2 | EMITTER | passive | Emitter terminal of the NPN transistor; also the low side of the internal base-emitter resistor R2. Typically tied to circuit ground in a low-side switch configuration. |+| 3 | COLLECTOR | passive | Collector terminal of the NPN transistor. Rated VCEO = 50 V, VCBO = 50 V, IC = 100 mA continuous. Connect through the load to the positive supply for a low-side switch. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LRC |+| Package | SOT-23 |+| Category | Transistors/Thyristors |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `LMUN2232LT1G`+- `LMUN2232LT1GS-LMUN2232LT1G`++## CAD (KiCad official)++- Symbol: `LMUN2232LT1G`+- 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/8586183129623511040) (5 pp, sha256 `f9f271a831308dc6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
