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 internal NPN transistor through the integrated base series resistor R1 = 2.2 kΩ; a shunt resistor R2 = 47 kΩ is connected between the internal base node and the emitter. |+| 2 | EMITTER | passive | Emitter of the internal NPN transistor. Typically tied to circuit ground in low-side switch configurations. Also serves as the return for the internal shunt resistor R2. |+| 3 | COLLECTOR | output | Collector output of the internal NPN transistor. Maximum collector current IC = 100 mA; VCEO = 50 V, VCBO = 50 V. Connect through a load to the supply for switching applications. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LRC |+| Package | SOT-23 |+| Category | Transistors/Thyristors |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `LMUN2235LT1G`+- `LMUN2235LT1GLT3G`++## CAD (KiCad official)++- Symbol: `LMUN2235LT1G`+- 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/8586187918629351424) (16 pp, sha256 `fbd038062603f087`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
