PDTA143ZU from Nexperia, in a SOT-323-3. 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 (base) of the built-in transistor, with the bias resistor R1 = 4.7 kΩ on the input; input voltage is limited to -30 V to 5 V. |
| 2 | GND | power_in | Ground reference pin connected to the emitter of the built-in transistor. |
| 3 | O | output | Output (collector) of the built-in transistor; output current is limited to -100 mA. |
