DTA114YE from Changjing, in a SOT-523. 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 of the built-in bias-resistor inverter, with a 10 kΩ input resistor (7 to 13 kΩ), and an input voltage rating of -40 V to +6 V for the DTA114Y family. |
| 2 | GND | power_in | Common ground reference for the transistor and its built-in bias resistors. |
| 3 | OUT | output | Collector output of the PNP digital transistor, rated for an output current of -70 mA and a peak collector current of -100 mA for the DTA114Y family. |
