HDTC144EKAT146 from HXY MOSFET, in a SOT-23-3L. 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 | IN | input | Base input of the built-in bias-resistor digital transistor; input voltage is rated from -10 V to +40 V per the maximum ratings. |
| 2 | GND | power_in | Ground reference terminal for the inverter circuit. |
| 3 | OUT | output | Output terminal of the digital transistor; output current is rated at 30 mA with a peak collector current of 100 mA. |
