HTDTA143ELM 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 of the built-in bias-resistor inverter; the datasheet gives the input voltage range as VIN -30 to +10 V (absolute maximum ratings). |
| 2 | GND | power_in | Ground reference pin for the device; the datasheet lists it in the SOT-23 pin assignment but states no specific voltage or current limit for it. |
| 3 | OUT | output | Output pin, rated for an output current IO of -100 mA maximum, with VO(on) of -0.3 V max at IO/II = -10 mA / -0.5 mA. |
