NHDTA124EUX from Nexperia, in a SOT-323. 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 R1 (22 kΩ typ for NHDTA124EU); input voltage limit -60 V to +10 V. |
| 2 | GND | power_in | Ground (emitter) of the transistor; the built-in R2 (22 kΩ typ for NHDTA124EU) is connected between input and this pin. |
| 3 | O | output | Output (collector) of the transistor, rated for collector-emitter voltage of -80 V (open base) and output current of -100 mA. |
