AD-DTA114YM from Changjing, in a SOT-723. 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 through built-in R1 (7-13 kΩ) to the PNP base, with input voltage rated -40 V to +6 V. |
| 2 | GND | power_in | Ground/emitter terminal, GND(+) in the equivalent circuit, which is the positive reference for this PNP digital transistor. |
| 3 | OUT | output | Collector output with output current rated -70 mA and supply voltage rated -50 V. |
