LMUN2232LT1G from LRC, in a SOT-23. 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. |
