NHDTC123JUX 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 pin (base) of the resistor-equipped transistor, connected through bias resistor R1, which is 2.2 kΩ for NHDTC123JU (Table 1 and Table 8). |
| 2 | GND | power_in | Ground pin, connected to the emitter of the built-in NPN transistor; bias resistor R2 (47 kΩ for NHDTC123JU) is connected between the input and this pin. |
| 3 | O | output | Output pin (collector) of the built-in NPN transistor, rated for a collector-emitter voltage VCEO of 80 V and an output current IO of 100 mA. |
