HDTC144EMT2L from HXY MOSFET, in a SOT-723. 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 through built-in bias resistor R1 (47 kΩ typ); input voltage range is -10 V to +40 V, with VI(off) min 0.5 V and VI(on) max 3 V. |
| 2 | GND | power_in | Ground connection, emitter side of the NPN digital transistor and return for resistor R2. |
| 3 | OUT | output | Output (collector) of the digital transistor, rated 30 mA continuous output current and 50 V supply voltage maximum. |
