PDTC144VT 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 transistor, connected to the built-in bias resistor R1 = 47 kΩ as shown in the graphic symbol. |
| 2 | GND | power_in | Ground connection serving as the emitter of the transistor, returning the R2 = 10 kΩ bias network to ground. |
| 3 | O | output | Output (collector) of the transistor, rated for an output current IO of 100 mA and a collector-emitter voltage VCEO of 50 V (open base). |
