MMUN2113LT1G 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 | Input pin driving the base through the integrated 47 kΩ series input resistor R1; the datasheet rates the input forward voltage VIN(fwd) at 40 Vdc and the input reverse voltage VIN(rev) at 10 Vdc. |
| 2 | EMITTER | power_in | Emitter tied to ground (labeled EMITTER (GROUND)) and connected to the base through the integrated 47 kΩ base-emitter resistor R2. |
| 3 | COLLECTOR | output | Output pin; the datasheet rates the collector-emitter voltage VCEO at 50 Vdc and the continuous collector current IC at 100 mAdc. |
