PDTA124XU 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 PNP resistor-equipped transistor, connected through built-in bias resistor R1 (22 kΩ typ, 15.4 to 28.6 kΩ); input voltage limits are -40 V to 7 V. |
| 2 | G | power_in | GND (emitter) of the transistor, reference for the input and output; emitter-base voltage rating is -7 V max (open collector). |
| 3 | O | passive | Output (collector) of the transistor with VCEO of -50 V max and output current of -100 mA max. |
