PDTA143ZT 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 (base) of the built-in PNP transistor, connected through the internal 4.7 kΩ bias resistor R1; the datasheet limits the input voltage to -30 V to 5 V. |
| 2 | GND | power_in | Ground pin, which is the emitter of the built-in transistor and the reference for the internal bias network R1 and R2. |
| 3 | O | output | Output (collector) of the built-in transistor, rated for an output current of -100 mA and a collector-emitter voltage of -50 V. |
