MMUN2111LT1G from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BASE | input | Base (input) pin of the bias-resistor transistor; the internal series input resistor R1 is 10 kΩ typical (7.0 to 13 kΩ), and the input forward voltage is rated to 40 Vdc with input reverse voltage limited to 10 Vdc. |
| 2 | EMITTER | power_in | Emitter pin, labeled GROUND on the datasheet, serving as the ground reference for the output stage and the base-emitter bias resistor R2 (10 kΩ). |
| 3 | COLLECTOR | output | Collector (output) pin; collector-emitter voltage is rated to 50 Vdc (VCEO) and continuous collector current to 100 mAdc. |
