DTA114EL-T92-K from UTC(Unisonic Tech), in a TO-92. 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 | GND | power_in | Ground pin of the DTA114E digital transistor (pin assignment G in the ordering table for the TO-92 DTA114EL-T92-K variant). |
| 2 | OUT | output | Output pin of the built-in bias-resistor transistor, rated for an output current IOUT(MAX) of -100 mA. |
| 3 | IN | input | Input pin of the built-in bias-resistor transistor, rated for an input voltage VIN of -40 to +10 V. |
