MMUN2216LT1G 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 is the BRT input, with a maximum input forward voltage VIN(fwd) of 30 Vdc and a maximum input reverse voltage VIN(rev) of 6 Vdc, and it drives the internal series base resistor R1 (4.7 k typical). |
| 2 | EMITTER | power_in | Emitter is the ground reference of the transistor and is labeled EMITTER (GROUND) in the datasheet pin connections. |
| 3 | COLLECTOR | output | Collector is the BRT output, rated for a maximum collector-base voltage VCBO of 50 Vdc, collector-emitter voltage VCEO of 50 Vdc, and continuous collector current IC of 100 mAdc. |
