HDTB143ECT116 from HXY MOSFET, 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 | IN | input | Input pin, rated at VIN -30 V to +10 V, and it connects to the built-in bias resistor (R1 typ 4.7 kΩ, range 3.29 to 6.11 kΩ) so the device works as an inverter without external input resistors. |
| 2 | GND | power_in | Ground reference pin; the datasheet does not state a voltage or current limit for this pin. |
| 3 | OUT | output | Output pin, rated at output current IO -100 mA, with output voltage VO(on) of -0.3 V max at IO/II = -10 mA/-0.5 mA. |
