**HXY MOSFET** · Digital Transistors · SOT-323

HMUN5233T1G from HXY MOSFET, in a SOT-323. 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 digital transistor, rated for an input voltage VIN of -5 to +30 V. |
| 2 | GND | power_in | Ground pin; the datasheet lists it only as GND and states no further electrical limits for it. |
| 3 | OUT | output | Output pin, rated for an output current IO of 100 mA maximum. |
