DTC123JCA from Changjing, 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 | IN | input | Input pin of the built-in bias-resistor inverter; the absolute maximum input voltage VIN is rated from -5 V to +12 V. |
| 2 | GND | power_in | Ground reference pin of the digital transistor. |
| 3 | OUT | output | Output pin of the digital transistor; the maximum output current IO is rated at 100 mA. |
