PDTA124ET-QR from Nexperia, 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 | I | input | Input pin (base) that drives the built-in transistor through bias resistor R1, which is 22 kΩ with a 15.4 to 28.6 kΩ range. |
| 2 | GND | power_in | Ground pin (emitter) of the built-in transistor. |
| 3 | O | output | Output pin (collector) of the built-in transistor, which is rated for an output current of -100 mA. |
