LMUN2235LT1G 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. 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. |
