HXY MOSFET · Digital Transistors · SOT-23
HDDTC143ECA7F 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 rating as -5 to +30 V. |
| 2 | GND | power_in | Ground reference pin for the digital transistor; the datasheet gives no additional limit for this pin. |
| 3 | OUT | output | Output pin of the digital transistor, rated for an output current of 100 mA maximum. |
