MMUN2232LT1G 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 input of the bias-resistor transistor, with a 4.7 kΩ series base resistor (R1); input forward voltage VIN(fwd) is limited to 30 Vdc and input reverse voltage VIN(rev) to 10 Vdc. |
| 2 | EMITTER | power_in | Emitter is the ground reference of the device, tied to the internal 4.7 kΩ base-emitter resistor (R2), and is labeled GROUND on the datasheet pin diagram. |
| 3 | COLLECTOR | output | Collector is the output of the transistor, rated for a collector-emitter voltage VCEO of 50 Vdc and a continuous collector current IC of 100 mAdc. |
